Print the first five numbers starting from I together with their squares.

`#include<stdio.h>#include<conio.h>Void main ( ){       Int  I;       Clrscr ( );       For (i=l; <=5; i++)       Printf (“\n  Number:  %5d  it’ s  Square:  %5d”, I, i*i);      getch();}`

OUTPUT:

Number:  1  it’ s  Square:  1

Number:  2  it’ s  Square:  4

Number:  3  it’ s  Square:  9

Number:  4  it’ s  Square:  16

Number:  5  it’ s  Square:  25

`#include<stdio.h>#include<conio.h>Valid main ( ){        Int  I;        Clrscr ( ) ;        For ( i=l; i<=15; i= i+l)        Printf (“%5d”,i);        getche ( );}`
