Convert String Into Upper Case in C

Introduction

In this tutorial, we will learn about Convert String Into Upper Case in C. 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 <ctype.h>

int main() {
    char str[] = "hello world";
    int i = 0;
    
    while(str[i]) {
        str[i] = toupper(str[i]);
        i++;
    }
    
    printf("Uppercase string: %s
", str);
    return 0;
}

Code Explanation

The code above illustrates the core logic required to implement Convert String Into Upper Case in C. By breaking it down, we can observe the following:

• Initialization: Proper setup of the variables and structures.
