How to check if Two Strings are Equal ignoring case in C - Step by Step Examples

How to check if Two Strings are Equal ignoring case in C ?

Answer

To check if two strings are equal ignoring case in C, you can use the strcasecmp function from the strings.h header file to perform a case-insensitive comparison.

✐ Examples

1 Equality Check Ignoring Case in C

In this example,

We include the strings.h header file.
We create two strings named str1 and str2 with different cases, such as "Hello" and "hello".
We use the strcasecmp function to compare the strings ignoring case.
The strcasecmp function returns 0 if the strings are equal ignoring case, and a non-zero value otherwise.
Finally, we check the result and print the appropriate message.

C Program

// Equality Check Ignoring Case in C
#include <stdio.h>
#include <strings.h>

int main() {
    char str1[] = "Hello";
    char str2[] = "hello";
    int result = strcasecmp(str1, str2);
    if (result == 0) {
        printf("Strings are equal ignoring case\n");
    } else {
        printf("Strings are not equal ignoring case\n");
    }
    return 0;
}

Output

Strings are equal ignoring case
