How to count strings and integers from an array of strings in C

Answer 1

#include <stdio.h>
#include <ctype.h>

void count_strings_and_integers(char *arr[], int size, int *totalintegers, int *totalstrings) {
    for (int i = 0; i < size; i++) {
        int is_digit = 1;
        for (int j = 0; arr[i][j] != '\0'; j++) {
            if (!isdigit(arr[i][j])) {
                is_digit = 0;
                break;
            }
        }
        
        if (is_digit) {
            (*totalintegers)++;
        } else {
            (*totalstrings)++;
        }
    }
}

int main() {
    char *arr[] = {"2", "99", "java", "34", "c++", "7", "python", "c", "890", "c#", "go"};
    int size = sizeof(arr) / sizeof(arr[0]);
    int totalintegers = 0, totalstrings = 0;
    
    count_strings_and_integers(arr, size, &totalintegers, &totalstrings);
    
    printf("%d\n", totalintegers);
    printf("%d\n", totalstrings);
    
    return 0;
}
