How to find the longest string size in array of strings in C

Answer 1

#include <stdio.h>
#include <string.h>
      
#define ROWS 5
#define COLS 10
  
int longest_string_size(char arr[][COLS]) {
    int max = strlen(arr[0]);

    for (int i = 1; i < ROWS; i++) {
        int size = strlen(arr[i]);
        if (size > max) {
            max = size;
        }
    }
 
    return max;
}
   
int main() {
    char arr[ROWS][COLS] = {"c++", "c#", "python", "java", "php"}; 
       
    printf("%d", longest_string_size(arr));
   
    return 0;
}
