C Basic Declarations and Expressions: Exercise-42 with Solution
Write a C program to print a number, it’s square and cube in a line, starting from 1 and print n lines. Accept number of lines (n, integer) from the user.
Pictorial Presentation:
Sample Solution:
C Code:
#include <stdio.h>
int main() {
int a, i, j = 1, x = 0;
printf("Input number of lines: ");
scanf("%d", &a);
for(i = 1; i <= a; i++) {
printf("%d %d %d\n", i, i*i, i*i*i);
}
return 0;
}
Sample Output:
Input number of lines: 5 1 1 1 2 4 8 3 9 27 4 16 64 5 25 125

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().
