Input an Array, Store the Squares of these Elements in an Array & Print it

#include

#include

#define max_rows 3

#define max_cols 4

void print_square(int [ ] );

void main (void)

    int i;

    int num [max_rows][max_cols] = { {10, 20, 30, 40}, {50, 60, 70, 80}, {90, 100, 110, 120} };

    for (i = 0; i < max_rows; i++)

        print_square(num[i]);

void print_square(int x[ ])

    int j;

    for (j = 0; j < max_cols; j++)

        printf ("%d\t", x[j] * x[j]);

    printf("\n");

    getch();

Output

100    400    900    1600

2500   3600   4900   6400

8100   10000  12100  14400

Print the Alternate Elements in an Array

#include

void main()

    int array[10];

    int i, j, temp;

    printf("enter the element of an array \n");

    for (i = 0; i < 10; i++)

        scanf("%d", &array[i]);

    printf("Alternate elements of a given array \n");

    for (i = 0; i < 10; i += 2)

        printf( "%d\n", array[i]) ;

 getch();

Output

            enter the element of an array
