Please help modify my C program to be able to answer these questions, it seems the spacing and some functions arn't working as planeed. Please do NOT copy and paste other work as the answer, I need my source code to be modified. Source code: #include <stdio.h> #include <string.h> #include <ctype.h> #include <stdlib.h> int main(void) { char title[50]; char col1[50]; char col2[50]; int point[50]; char names[50][50]; printf("Enter a title for the data:\n"); fgets (title, 50, stdin); printf("You entered: %s\n", title);...
Within this C program change the input to a file instead of individual input from the user. You must take the input file name on the command line. Be sure to have simple error checking to be sure the file exists and was successfully opened. The input file will have the following format: First line: Number of students Second Line: Number of grades Third Line: Student Names, space delimited Fourth+ Line(s): Grades for all students for one assignment, space delimited....
The program reads an unknown number of words – strings that all 20 characters or less in length. It simply counts the number of words read. The end of input is signaled when the user enters control-d (end-of-file). Your program prints the number of words that the user entered. ****** How do you I make it stop when control-d is entered. My code: #include <stdio.h> void main(void) { char sentence[100]; int i = 0; int count = 1; printf("Enter a...
