✐ Examples

1 Iterate over Characters in String using for loop

In this example,

We create a character array named str with a value of {'C', 'P', 'L', 'U', 'S'}.
We use a for loop with an index variable i to iterate over the array length.
Within the loop, we access each character using array indexing str[i].
Finally, we print each character to the console.

C Program

#include <stdio.h>
int main() {
    char str[] = {'C', 'P', 'L', 'U', 'S'};
    for (int i = 0; i < sizeof(str) / sizeof(str[0]); i++) {
        printf("%c\n", str[i]);
    }
    return 0;
}

Output

C
P
L
U
S
