90. Implement Custom strlen Function

#include <stdio.h>
#include <stdint.h>
#include <string.h>
int custom_strlen(const char *str) {
    // Your logic here
    int count =0;
    while (*(str++) != NULL)
    {
        count ++;
    } 
    
    return count;
}

int main() {
    char str[101];
    fgets(str, sizeof(str), stdin);

    // Remove newline if present
    int i = 0;
    while (str[i] != '\0') {
        if (str[i] == '\n') {
            str[i] = '\0';
            break;
        }
        i++;
    }

    printf("%d", custom_strlen(str));
    return 0;
