C :: Program That Reads Alphanumeric Characters And Computes Average ASCII Value
Feb 16, 2015
Write a program that reads alphanumeric characters from the keyboard, and computes the average ascii value of the alpha numeric characters, the average alphabetical character, the average numeric character and the average uppercase character. Outputting each, you program should terminate reading once it read a non-alphanumeric character.
Here's what i have so far.
Code:
#include <stdio.h>
#include <ctype.h>
int main(void) {
int value = 'a';
int digit_loop = 0;
int alpha_loop = 0;
int upper_loop = 0;
[Code] ....

Here is my code and basically these are the steps. I feel like we have something good to work on but we keep getting errors.
a. Data to the program is input from a file of an unspecified length; that is, the program does not know in advance how many numbers are in the file.
b. Save the output of the program in a file.
c. Modify the function getNumber so that it reads a number from the input file (opened in the function main), outputs the number to the output file (opened in the function main), and sends
the number read to the function main. Print only 10 numbers per line.
d. Have the program find the sum and average of the numbers.
e. Modify the function printResult so that it outputs the final results to the output file (opened in the function main). Other than outputting the appropriate counts, this new definition of the function printResult should also output the sum and average of the numbers.

I'm writing a program that reads and counts all the printable characters (ASCII 32-126)found in a text file.
For example if the text file read: Why so serious?
The output to the screen would display(in order of ascii value however):
Character-----Total
W--------------1
h--------------1
y--------------1
s--------------3
o--------------2
etc...
However, I don't think it's reading any of the characters.
#include <iostream>
#include <iomanip>
#include <fstream>
#include <cmath>
#include <string>
using namespace std;
int main() {
int i, count[127];

The output should also give a file which doesnt consits alphanumeric. I tried this
while( ( ch = fgetc(fp) ) != EOF ){
if(isalpha(ch)||ch==' ')
Is this correct.than how to complete it.

I am looking for a way to sort a string just by the alpha characters, not by the ASCII table. Therefore
string sort(string name) {
sort(name.begin(), name.end());
return name;
}
will not work. And I am looking for the most simple way to go about it!

I'm trying to write a lot of sample code to practice but I can not figure out how to take a string and sort each character in order of their increasing ASCII codes. I'm getting stuck trying to separate each letter to determine it's ASCII code. I know I have to use an array somehow, So far, this is my code:
#include <stdio.h>
#include <stdlib.h>
#define _CRT_SECURE_NO_WARNINGS

#include<iostream>
#include<conio.h>
using namespace std;
int main(void){
clrscr();
[Code] ....
I am trying to print ascii characters but problem is If i put a limit in for loop to 255 or more than 126 the output don't stop it keeps on going
I know there is another way to this program but what i want to know this why this happen in this logic....it doesn't happen if a<=125 or less then 125.

What shall I learn in order to send values from 0.00 to 5.00? I'm working with they Hitachi 16x2 LCD display.I've been sending/displaying literal values on it all day.
Code:
SendCharater(unsigned char val)
where the variable val corresponds to the LCD character table.I can also send Hello World to the display, like so:
Code:
void putsXLCD(unsigned char *buffer){
while(*buffer) // Write data to LCD up to null
{
while( BusyXLCD() ); // Wait while LCD is busy
SendCharacter(*buffer); // Write character to LCD
buffer++; // Increment buffer
}
return;
}
I could type in putsXLCD("5.00") in order to display it on the LCD, but how do I implement this automatically for values, e.g. 0.00 to 5.00?It appears I can only pass literal values through the function SendCharacter, meaning that in order to display "0" I have to pass the value 0x30 (the hex value of "0" on the LCD Table).
My current thought process:Much like passing "Hello World" in the function putsXLCD(), I need to assign a pointer that points at each value in the "array" that I need to send. E.g., I need to send 3.24, so I need to point to "3", fetch the corresponding hex value in the LCD table, in this case 0x34, and the pass this 0x34 into the SendCharacter function, and so on. So, if this is the case, how can I fetch the corresponding hex value?

write a program that computes the factorial of a number and displays it. A factorial of a number (written N!) is defined as N * (N-1) * (N-2) * (N-3) ... *1 In other words, 5! = 5 * 4 * 3 * 2 * 1 = 120 and 3! = 3 * 2 * 1 + 6.
Example of output 15 is 1.30767e+012
Can't get it to display error when user enters a number lower than 2 or higher 60.

The code is supposed to convert characters from an array into their respective ascii integers, and append a 0 if the number is less than 3 digits long. It then supposed to put it all together into one string.
Code:
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
int main(void){
char file[] = "This is a test";
char *ptr = file;
int length = strlen(file);
int i, numbers[length];

and O/P I get is
Enter phone number: CALLAT
/**blank space***/

Write a program that reads in ten whole numbers and that output the sum of all the numbers greater than zero, the sum of all the numbers less than zero (which will be a negative number or zero), and the sum of all the numbers, whether positive, negative, or zero. The user enters the ten numbers just once each and the user can enter them in any order.
Your program should not ask the user to enter the positive numbers and the negative numbers separately. Assume the user will type integer numbers.
this is what i got but it wont run saying there is an error
#include<iostream>;
using namespace std;
int main() {
int count=0;
int num;
int positive=0;
int negative=0;

I started to write a program that repeatedly reads in values for a,b and c and find the root of the polynomial
ax^2 + bx + c = 0
The program should print out for example:
two complex roots: root1 = -1.00000 + i*1.41421
root2 = -1.00000 - i*1.41421
My code:
#include <stdio.h>
#include <math.h>
int main(void){
int a,b,c;
printf("Choose the values of a, b and c for the equation ax^2 + bx + c");
scanf("%d%d%d
",a,b,c);

I've been working on a program that displays the number of digits in each line of a file, but I feel stuck. Take for example a file that contains these characters:
6347aaa9
54j
811111
6a
709
And I'm trying to display a result like this
1 //that's the number of the line 5 //the number of digits
2 2
3 6
4 1
5 3
Here's what I've written so far:
Code:
#include<stdio.h>
int main() {
char a=0;
int number_of_digits=0, linescount=0, num, number_of_digits_per_line=0;
FILE *inputFile;
if(!(inputFile=fopen("C:TestTest.txt","r")))
[Code]..
I also thought of using fgets and strlen but I am not very good with them and couldn't get the program to work correctly. It did work but it displayed all characters, letters included, not only digits.

Write a program that reads data from a file (use the attached data file). These data are a student name and 3 test scores. The program should calculate the average of the 3 test scores, and display the name, 3 test scores, and the average to the monitor.
Useful tips:
a) Include the following header files: iostream, fstream, iomanip, and string
b) The name of the data file is “datafile.txt”, you need to save the file in the same folder of the source file.
c) use the manipulators (setw, setprecision, setfill, showpoint, fixed) to format the average with 1 digits after decimal point as following.
d) Use character ‘ ’ for tab.

c++ program that reads in a sequence of binary digits (values 0 and 1) and stores them into a STL container. The input should terminate on any input that is not a 0 or 1. After finishing the read-process, apply a "bit-stuffing" algorithm to the container. In this case the bit stuffing should occur after four consecutive bits of the same value.i,e. four 0's or four 1's.. Also write the de-stuffing code to process the stuffed data to recreate the original data and verify that the original data is recovered correctly.

I'm not sure why Im getting a wrong Sum. of the Columns.
Write a method that returns the sum of all the elements in a specific column in a matrix using the following header:
double sumColumn(const double m[] [SIZE], int rowSize, int columnIndex)
Write a test program that reads a 3-by-4 matrix and displays the sum of each column. here is a sample run:
Enter a 3-by-4 matrix row by row:
1.5 2 3 4
5.5 6 7 8
9.5 1 3 1
Sum of the elements at column 0 is 16.5
Sum of the elements at column 1 is 9.0
Sum of the elements at column 2 is 13.0
Sum of the elements at column 3 is 13.0

Write a program that prompts for and reads in test scores. You may assume that valid test scores will be integer values between 0 and 100. You may also assume that the user will not enter more than 35 test scores. Use a preprocessor directive to define this value. User input will be complete when the user enters a -1 for the test score. When all of the test scores have been entered, the program will print out the scores. Use a while or do-while loop to read in the values. Use a for loop to print out the values.
Sample output:
Enter test score 1: 88
Enter test score 2: 67
Enter test score 3: 74
Enter test score 4: 94
Enter test score 5: 79
Enter test score 6: 56
Enter test score 7: -1
Number of scores entered: 6
Test scores entered : 88 67 74 94 79 56

" Write a program that reads into a string object a name with three blanks between the first and last names. Then extract the first and last names and store them in separate string objects. Write a function subprogram that displays its string argument two times. Call this function display the first name for times and then to display the last name six times."
I completed coding the first part of this task with the strings and combining strings together. However, i have having trouble with the other half of this task. It begins from "Write a function subprogram to display the last name six times." This is where i have so far --

This is what the notepad file looks like
-----------------------------------

Why does it give me random numbers in the output rather than what the notepad has?
Also, the outfile is completely blank.

I'm trying to make a program that reads data from a text document and allows me to modify it. I am stuck with the display() function. I can get the printf statement to display all my array values except the char AD value. When I include flight[i].AD it causes the program to crash. When I run the program to only display the AD variable I get a bunch of weird symbols. I'm not sure where the program is going wrong because it seems to be storing values properly except for the AD variable.
#include <fstream>
using namespace std;
//named constants
const int MAX=100; //maximum flights
const int SIZE=20; //maximum characters
//struct definition
struct FlightType
{
char name[SIZE];
