✐ Examples

1 Check if String contains specific Character using loop

In this example,

We create a function 'containsCharacter' that takes a string and a character as input.
We loop through each character in the string and check if it matches the target character.
If a match is found, we return 'true'; otherwise, 'false'.
Finally, we print the result.

C Program

#include <stdio.h>
#include <stdbool.h>

bool containsCharacter(char *str, char ch) {
    while (*str) {
        if (*str == ch) {
            return true;
        }
        str++;
    }
    return false;
}

int main() {
    char str[] = "Hello World";
    char ch = 'W';
    bool contains = containsCharacter(str, ch);
    printf("String contains character '%c': %d\n", ch, contains);
    return 0;
}

Output

String contains character 'W': 1
