C/C++ :: Program To Read In And Count All Printable Characters (ASCII 32-126)
Feb 12, 2014
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];
[Code] .....

My program is find non printable ASCII value(1 to 32) and calculate count from a text like "hi<tab>this<space>my text.i'm using library file here.(visual studio 2012)
removeascii.h(program name)
#pragma once
#include<stdint.h>
#include <string>
using std::string;
namespace ascii
[Code] ....
My ERROR is:
1>c:program files (x86)microsoft visual studio 11.0vcunittestincludecppunittestassert.h(65): error C2338: Test writer must define specialization of ToString<const Q& q> for your class class std::basic_string<wchar_t,struct std::char_traits<wchar_t>,class std::allocator<wchar_t> >

We have to make a code to detect the frequency of printable characters. But when I run the code, sometimes it can't detect the Uppercase Letters. But it can sometimes. It's a bit buggy, and it really can't get the frequency of the space character.
Does textcolor affect the outcome?
Code:
#include<stdio.h>#include<conio.h>
int main ()
{
clrscr();
char name[40],sentence[1000],ch;
int c=0,count[95]={0};
textcolor(LIGHTCYAN);
[Code] ....
I also noticed that it stops detecting the frequency when there is a space between character/s.

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] ....

My goal is to create a program that reads a string and counts how many Uppercase, Lowercase, Spaces, and digits there are in the string. Right now this the output i get.
#include <stdio.h>
#include <stdlib.h>
#include <ctype.h>
int main() {
int iochar;
char string;

#include <stdio.h>
#include <string.h>
int main() {
char string[100];
int c= 0, count[26] = {0};
printf("Enter a string: ", string);
[Code]...
This is the output I receive:
I need counting the Uppercase Letters.

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

I have a .txt file that contains, together with a few characters, columns of values that I want to save in different files like is written in the program (file 1, file2, file3 - a with x, b with y, c with z). The pattern of the source text file is like this:
known_vector frame1 151 65 0 frame2 151.000763 64.538582 0.563737
known_vector frame1 152 65 0 frame2 152.000702 64.542488 0.560822
known_vector frame1 153 65 0 frame2 153.000671 64.546150 0.558089
Until now I could manage to split the files, but the output gives me only zeros. First the program count the number of lines of the read text file, then it should display the desired columns of double values in three other .txt files.I've got for the three .txt files columns like this:
0.000000 0.000000 0.000000 0.000000 0.000000 0.000000
0.000000 0.000000 0.000000 0.000000 0.000000 0.000000
0.000000 0.000000 0.000000 0.000000 0.000000 0.000000

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?

4.1 Write a program that will count from 1 to 12 and print the count, and its square, for each count.
4.2 Write a program that counts from 1 to 12 and prints the count and its inversion to 5 decimal places for each count. This will require a floating point number.
4.3 Write a program that will count from 1 to 100 and print only those values between 32 and 39, one to a line. Use the incrementing operator for this program.

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];

I'm supposed to write a program to read a text file and display the following:
a) alphabetic letters //finished with
b) digits // finished with
c) other characters that are not alphabetic letters and not digits //finished with
d) total characters read
The bold part above confused me, by total characters, does it mean the alphabetic letters + other characters? how would I put that in my code?
Code:
#include <stdio.h>
int main (void)
{
int curCh;
int countCh = 0;

I wrote a function to count the number of characters in a string. Curious as to why I have to return x-1 and why x isn't the number of characters.
Code:
int count(char *string){
55 int x = 0;
56 char *p;
57 p = string;
58

I want to setup my MFC-based dialogue "IDD_LOADCELL" with serial communication so that when that dialogue is pop up, the data from PIC (external device) which is in hex file format is display on the edit control box on the dialogue. The variable name of the edit control box is "m_loadP "and "m_loadT1". type of variable for both are string. I want to get the code for the COMPort setting and reading the data from pic and finally display it on the edit control box created on the dialogue.

My problem is to count the characters in a file and define how many times each one occurs.Characters who are not found must not be included in the table; The output must be a table - like that -
”| character | ASCII- DEC | ASCI – HEX | how many times it occurs |”
This my function:
Code:
int f2(FILE *p1)
{
FILE *g3;
int char_count[256]={0};
char ch;
int n=0;
if(!(g3=fopen("D:zz.txt", "w"))){
[Code] ....
It must look like this:
| D | 68 | 44 | 2 |
| 2 | 50 | 32 | 1 | and so on...

#include<iostream.h>
#include<conio.h>
#include<stdio.h>
void count();
void main() {
char c[100];
cout<<"Enter a string upto 99 characters(spaces included):"<<endl;
[Code] ....
The thing is, when I don't create a prototype of count and straightaway define it before void main() my program runs, but it gives error in this program that "extra parameter in call to count()" But what to do then?

I'm trying to create a program that counts the amount of alphabetical characters, numbers, blanks and total amount of characters in a string a user gets to enter. The user also quits the program manually by pressing CTRL + D (in linux terminal).
These are the results I get from the code so far by typing in "hello cplusplus 123 c++" CTRL + D.
The string had:
Alphabetical characters...: 0
Numbers...................: 0
Blanks....................: 3
Total amount of characters: 20
So I can't seem to find a way to count the amount of alphabetical characters and numeric characters.
Here's my code:
#include <iostream>
#include <string>
#include <iomanip>
#include <cctype>
#include <sstream>
using namespace std;
int main() {
string tecken;
[Code] ....
The reason why I declared cctype is that I think I should use the isalpha, isdigit and isblank functions but how I am supposed to do that.

This is a small program that reads a line from the screen, takes the ASCII values from the entered text, and edits it. Next, the ASCII values are reinterpreted (am i misspelling?) as text, and displayed. However, my final output has (allways?) at least 7 characters, even if you enter only one. I'm also trying to accomplish, that the part of the string which isn't filled, will be printed empty. In spaces.
compiled with -std=c99.
Code:
#include <stdio.h>
int main(){
int maxsize;
printf("How long is your message?

Why TAB with ASCII value 9 is non printable character and SPACE with ASCII value 32 is printable?I can open any editor and press any of them and I see it on screen(If I press tab cursor is moved by tab, and space if I press space)....
Then why one of them is printable and other non printable?
