I would like the following code to print: "Why doesn't this print?" and "I would like to print the sum of nc: 5". What am I doing wrong.
#include <stdio.h> //Use to test ideas and formats// main() { int c, nc; nc = 0;
[code]....
My result as compiled by gcc -o testing testing.c
This prints.
test t1,e2,s3,t4, 5,
I have not figured out how to sum and print as the above code indicates, which complicates my ability to do many of the exercises in "The C Programming Language". I am using a MacBook gcc compiler and X code as well. I cannot get the last two printf functions to work. I did the temperature example with "while (fahr <= upper)" and the printf printed.
This is supposed to output t=m and then m is plugged into a function say for -3, plugging it into function f gives 23, well i want 22 blank spaces and then a asterik and go to next line. that is why i put -1 after %'f(m)-1's i
The asterisk appear right next to the t value here but they are way to the right of it when i made this post.
How to print to the screen the value of n after it has been multiplied.
For example: if I use cout << "n: " << n << " power: " << power << " "; I
can see the variable "power" decrementing by 1, but I don't see the variable "n" incrementing with its new value after it has been multiplied by n * n.
#include <iostream> using namespace std; typedef unsigned short int USHORT; typedef unsigned long int ULONG;
fstream infile1(argv[1]); if(!infile1.is_open()) cout << "Could not open file"; else { char listNum; while(infile1.get(listNum)) cout << listNum; }
However, when I check for odd or even numbers it will check each and every number.
printed like this (partial list): 1 is odd 3 is odd 8 is even 9 is odd
But it should print: 138 is even 9 is odd
I tried using getline, but it keeps giving me the errors: invalid conversion from 'void*' to 'char**' invalid conversion from 'char' to 'size_t*' too few arguments to function 'ssize_t getline(char**, size_t*, FILE*)'
Here is the getline code, what am I doing wrong? I have tried switching things around, adding things. Just nothing works.
ifstream infile1(argv[1]); if(!infile1.is_open()) cout << "Could not open file"; else { char listNum; getline(infile1, listNum); cout << listNum; }
Given this sentence as an input: "Hello my name and "John" (with its spaces and capital letters), print it on the screen .. NB the phrase must be entered from the keyboard all at once ... you can do this in C / C + +?
I'm trying to write a program that prints all of the prime numbers to the screen. I'm getting angry because it only prints EVERY number. I think it has something to do with the bool change not being able to leave the for-loop but how to fix it.
Code: #import <stdio.h> #include <stdbool.h> int main(void){ printf(" The Primes Are: 1");
i am programming Cli/Ser ,so part of the program is to open file to download it from client side,but i want to return the global value Errorno to print it to screen , and how to use strerror() func ??? i write this "This is part of server code" :
Code:
fd= open("abc.txt",O_RDONLY); //error handilng in open file if(fd<0) {
This seems simple enough but I'm missing something here to make this code work.What I'm trying to do is print the contents of the two dimensional array in 25 rows and 4 columns. I experimented with something similar to this code when I initialized the array with numbers.
I'm getting garbage. I tried including the name of the array in the cin object but I got an error message that says "no match for operator '>>'. When I take the name of the array out, the program compiles but I get garbage. Program is suppose to reads data from a file of 25 students and calculates test scores and class grade average output each student's name score, letter grade and grade average. I would be happy at this point if I could just print out something that wasn't garbage.
Here is the code.
#include <iostream> #include <iomanip> #include <cmath> #include <string> #include <fstream> using namespace std; //const const int Array_Row = 25; const int Array_Col = 4;
I have a text file where in each line is 3 words and 2 int type numbers. I'm doing search by word and I want to print out to the screen the whole line where that word was found (the words is repeated in some lines). My search looks like this:
Code: #include<iostream> #include<string> #include<fstream> #include<stdlib.h> #include <vector> using namespace std; int main(){ vector <string> words; string str, paieska;
I am trying to automatically(periodically) print screen a custom area of the screen, save it as an image file (the image will have the same format always), and then use OCR to get the text in the image as usable string variables. Is this doable? I was looking into tesseract OCR but I find it a bit unclear.
I am trying to make a program that will convert a list of binary numbers from a file into decimal and print the decimal to the screen. I have no problem doing the conversion, the problem comes up when our teacher wants the input file in a format as such:
3 10110101 11111111 10101010
The first number is supposed to tell the program how many different 8bit strings it is going to have to convert, and then the following lines are those binary numbers.
I am not very experienced with file inputs, and I know how to open files and read lines in.. The problem is, how to say "ok the first line says 3, so now I have to convert the next 3 lines" . I am assuming it is just a simple loop that I am missing....
Basically this is what i need to do. Write a program that reads a number from the keyboard, separates it into its individual digits and prints the digits to screen, each on its own line followed by the same number of stars as itself.
For example, if the number is 2339 the program should print
9 ********* 3 *** 3 *** 2 **
So far i have managed to separate the number and have them on different lines, but how to implement the stars onto each line with the number!
My code so far:
int main() { int n; printf("number? "); scanf("%d", &n); while (n > 0) { printf(" %d
comparing with screen size the height is bigger but lenght is smaller. I don't understand.
I can understand that different printers process the fonts in different way and then to have different lenghts. That's not the problem. The problem is I need to simulate in screen the same behaviour i will have on printer because these texts are being aligned in the document, and I don't want to see that the text si aligned different in text than in paper.
What can I do to render the text on screen with the same size I will have on the printer? Print preview is doing it. Should I change the font parameters? is something related with pixels per inch?
I am having a hard time with some of my homework, specifically regarding how to printf floats. I can't seem to print the number i want out using float, it just becomes a jumbled mess.
Thats the code I currently have, I've probably tried everything to get the number to come out, but I just cant seem to figure it out. It should look like this, but with different numbers and stock:
#include <stdio.h> struct database { int id_number; int age; float salary;
[Code] ....
When I compile, I get an error: test.c|18|error: incompatible type for argument 1 of 'printf'| note: expected 'const char *' but argument is of type 'float'|
I thought employee.salary is a float but the compiler expected 'const char'. How do I make this work?
