c check first character of string

Checking the First Character of a String in C

To check the first character of a string in C, you can use array indexing. Here's a simple example:

#include <stdio.h>

int main() {
    char str[] = "example";

    if (str[0] == 'e') {
        printf("The first character is 'e'\n");
    } else {
        printf("The first character is not 'e'\n");
    }

    return 0;
}

In this example, we declare a character array str and initialize it with the string "example". We then use str[0] to access the first character of the string and compare it with the character 'e'. Depending on the comparison, we print the appropriate message.
