Question

How to find the shortest string in array of strings in C

Answer 1

#include <stdio.h>
#include <string.h>
    
#define ROWS 5
#define COLS 10

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