C Program to Write a String in File

Introduction

In this tutorial, we will learn about C Program to Write a String in File. This is a crucial concept widely used in software development.

Implementation Example

Here is the complete source code to demonstrate how this works in practice:

#include <stdio.h>
#include <stdlib.h>

int main() {
    FILE *fptr;
    char str[100];
    
    fptr = fopen("output.txt", "w");
    if(fptr == NULL) {
        printf("Error opening file!");
        exit(1);
    }
    
    printf("Enter a string: ");
    fgets(str, sizeof(str), stdin);
    
    fprintf(fptr, "%s", str);
    fclose(fptr);
    printf("String written to output.txt successfully.
");
    
    return 0;
}

Code Explanation

The code above illustrates the core logic required to implement C Program to Write a String in File. By breaking it down, we can observe the following:

• Initialization: Proper setup of the variables and structures.
• Processing: Applying the core algorithm to achieve the result.
• Output: Printing the final results clearly.
