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 prints the squares and cubes of the numbers from 0 to 20 and 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");
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 15 225 3375 16 256 4096 17 289 4913 18 324 5832 19 361 6859 20 400 8000

C Programming: Tips of the Day
Static variable inside of a function in C
The scope of variable is where the variable name can be seen. Here, x is visible only inside function foo().
The lifetime of a variable is the period over which it exists. If x were defined without the keyword static, the lifetime would be from the entry into foo() to the return from foo(); so it would be re-initialized to 5 on every call.
The keyword static acts to extend the lifetime of a variable to the lifetime of the programme; e.g. initialization occurs once and once only and then the variable retains its value - whatever it has come to be - over all future calls to foo().
