Answer 1

#include <stdio.h>
#include <string.h>

int main() {
    const char *arr[] = {"c", "c++", "c#", "java", "python", "swift"};
     
    int rows = sizeof(arr) / sizeof(const char *);
    int columns =  sizeof(arr[0])/sizeof(arr[0][0]);
 
    printf("rows = %d\n", rows);
    
    for (int i = 0; i < rows; i++)
        printf("columns %d = %d\n", i, strlen(arr[i]));
}
 
 
 
/*
run:
 
rows = 6
columns 0 = 1
columns 1 = 3
columns 2 = 2
columns 3 = 4
columns 4 = 6
columns 5 = 5
