C Program to Find Factorial of a Number

main()
{
          int i, num, fact = 1;
          printf("Enter a number”);
          scanf("%d", &num);

          for (i = 1; i <= num; i++)
                    fact = fact * i;

          printf("Factorial of %d = %d\n", num, fact);
 }

C program to Generate Multiplication Table

main()
{
          int i, num;
          printf("Enter a number”);
          scanf("%d", &num);

          for (i = 1; i <= 10; i++)
                    printf(“%d * %d= %d”,num,i,num*i);
         
 }

C program to calculate the Power of a Number

main()
{
          int i, base,exp, power = 1;
          printf("Enter base and exponent ”);
          scanf("%d %d", &base, &exp);

          for (i = 1; i <= exp; i++)
                    power = power * base;

          printf(" %d  power  %d is :%d\n", base,exp,power);

 }

Write a c program to find out NCR factor of given number

main()
{
         
          printf(“Enter n and r values”);
          scanf(“%d %d”,&n,&r);

          printf("%ld ",factorial(n)/(factorial(r)*factorial(n-r));
}

long factorial(int n)
{
          int c;
          long int result =1;
          for(c=1;c<=n;c++)
                    result=result * c;
          return result;
}
