C Program to Calculate whether entered year is leap year or not


#include
main()
{
int year;
clrscr();
printf("\n enter the year");
scanf("%d",&year);
if(year%4==0 && year%100!=0)//(year%400==0)
printf("\n%d is a leap year \n");
else
printf("\n enter year is not leap year\n");
getch();
}

C Program to Check whether number is positive, negative, even or odd

#include
#include
void main()
{
int n;
clrscr();
printf("enter the no");
scanf("%d",&n);
if(n>0)
{
printf("\nnumber is +ve");
if(n%2==0)
printf("\n number is even");
else
printf("\n number is odd");
}
if(n<0)
printf("\n number is -ve");
getch();
}

C Program to calculate power of number

#include
#include
void main()
{
float x,power=1,i;
int y;
clrscr();
printf("enter the base and power values ");
scanf("%f%d",&x,&y);
for(i=1;i<=y;i++)
power*=x;
printf("\n%f raised to %d is %f",x,y,power);
getch();
}

C Program To check whether number is armstrong or not


#include
main()
{
int n,tot=0,tmp,d;
clrscr();
printf("\n enter the number");
scanf("%d",&n);
tmp=n;
while(n>0)
{
d=n%10;
tot=(d*d*d)+tot;
n=n/10;
}
if(tmp==tot)
printf("\n enter number is armstrong");
else
printf("enter number is not armstrong");
getch();
}
