C Exercises: Calculate and prints the squares and cubes of the numbers from 0 to 20

C Basic Declarations and Expressions: Exercise-76 with Solution

Write a C program to calculate and print the squares and cubes of the numbers from 0 to 20. It uses tabs to display them in a table of values.

Sample Solution:

C Code:

#include<stdio.h>
int main()
{
    int x;
    
    /* Print column names */
    printf("Number\tSquare\tCube\n");
    printf("=========================\n");

    // Loop to calculate and print squares and cubes
    for(x=0; x<=20; x++)
        printf("%d\t%d\t%d\n", x, x*x, x*x*x);
    
    return 0;
}

Sample Output:

Number	Square	Cube
=========================
0	0	0
1	1	1
2	4	8
3	9	27
4	16	64
5	25	125
6	36	216
7	49	343
8	64	512
9	81	729
10	100	1000
11	121	1331
12	144	1728
13	169	2197
14	196	2744
