How can you access each character of a string in the C language?

In C language, you can access each character of a string by using an array. Each character can be accessed by its index, starting from 0.

The following is a sample code that demonstrates how to access each character of a string:

#include <stdio.h>

int main() {
    char str[] = "Hello, World!";
    int i;

    for(i = 0; str[i] != '\0'; i++) {
        printf("%c ", str[i]);
    }

    return 0;
}

The output result is:

H e l l o ,   W o r l d !

In the example above, we used a for loop to iterate through the string `str`. The loop’s condition is `str[i] != ‘\0’`, meaning it will continue to execute until it reaches the end of the string (the null character ‘\0’). In each iteration, the `printf` function is used to print the character at the corresponding index `str[i]`.

It is important to note that in the C language, strings end with a null character ‘\0’, indicating the end of the string. Therefore, we can use ‘\0’ as a loop condition to determine if the string has ended.
