Find the Length of a String in C

#include <stdio.h>
int main() {
    char s[] = "Code of Code is a great website";
    int i;
    for (i = 0; s[i] != '\0'; ++i);
    printf("Length of the given string = %d", i);
    return 0;
}

Length of the given string = 31

• This program is used to determine the length of a string without using the function strlen().
• In main(), a string array s[] in initialized and an integer variable i is declared.
• A for loop is initialized which iterates between the characters of the string starting from i = 0 and continues iterations a null character is observed.
• In every iteration, the value of i is incremented by one.
• The length of the string is therefore stored in the variable i which is then printed.
