Program of factorial of a numbers

Solution: through for loop

void main()
{
    int a,n,power = 1;
    int i;
    printf("Enter the number:");
    scanf("%d",&a);
    printf("Enter the Power: ");
    scanf("%d",&n);

    for(i=1;i<=n;i++)
    {
        power = power*a;
    }

    printf("%d raise to the power of %d is %d",a,n,power);


}

Output1

Enter the number:5

Enter the Power: 5

2 raise to the power of 5 is 32.

Output2

Enter the number:5

Enter the Power: 3

5 raise to the power of 3 is 125.

Output3

Enter the number:3

Enter the Power: 5

3 raise to the power of 5 is 243.

Solution : through while loop

void main()
{
    int a,n,power = 1;
    int i;
    printf("Enter the number:");
    scanf("%d",&a);
    printf("Enter the Power: ");
    scanf("%d",&n);

    i=1;
    while(i<=n)
    {
        power = power*a;
        i++;
    }

    printf("%d raise to the power of %d is %d",a,n,power);


}

Solution: from do-while loop

void main()
{
    int a,n,power = 1;
    int i;
    printf("Enter the number:");
    scanf("%d",&a);
    printf("Enter the Power: ");
    scanf("%d",&n);

    i=1;
    do
    {
        power = power*a;
        i++;
    }while(i<=n)

    printf("%d raise to the power of %d is %d",a,n,power);


}

defining a function 'powers' which will return a raise to power n.

int powers(int a,int n)
{
    int pow=1,i;

    for(i=1; i<=n; i++)
    {
        pow = pow * a;
    }
    return pow;
}

Using above define function 'powers':

void main()
{
    int a,n,power;

    printf("Enter the number:");
    scanf("%d",&a);
    printf("Enter the Power: ");
    scanf("%d",&n);


   power = powers(a,n);
    printf("%d raise to the power of %d is %d",a,n,power);


}

Output1

Enter the number:5

Enter the Power: 5

2 raise to the power of 5 is 32.

Using above define function 'powers':

void main()
{
    int a,n,power;

    printf("Enter the number:");
    scanf("%d",&a);
    printf("Enter the Power: ");
    scanf("%d",&n);


   power = powers(a,n);
    printf("%d raise to the power of %d is %d",a,n,power);


}

Output2

Enter the number:5

Enter the Power: 3

5 raise to the power of 3 is 125.

Using above define function 'powers':

void main()
{
    int a,n,power;

    printf("Enter the number:");
    scanf("%d",&a);
    printf("Enter the Power: ");
    scanf("%d",&n);


   power = powers(a,n);
    printf("%d raise to the power of %d is %d",a,n,power);


}

Output3

Enter the number:3

Enter the Power: 5

3 raise to the power of 5 is 243.
