  32. C program to find the factorial of the given number.
    The product of a given positive integer multiplied by all lesser positive integers: The quantity five factorial (5!) = 5x4 x 3 x 2 x 1 = 120.
    33. #include <stdio.h> int main() { int num,i,f=1; printf("Enter any number : "); scanf("%d",&num); for(i=num;i>=1;i--) { f=f*i; } printf("\n Factorial of %d is %d",num,f); return 0; }

  34. C program to check whether the supplied number is prime or composite.
    35. A prime number is an integer which has only two factors i.e. one and itself. For example: 17 is prime number because it is exactly divisible by 1 and 17 only.
    #include <stdio.h> int main() { int num,i,count=0; printf("Enter a number"); scanf("%d",&num); for( i=1;i<=num;i++) { if(num%i==0) count++; } if(count==2) printf("%d is prime number",num); else printf("%d is composite number",num); return 0; }

  36. C program that asks a multi-digit number and calculates the sum of its individual digits.
    37. #include <stdio.h> int main() { int num,r,sum=0; printf(" Enter any number "); scanf("%d",&num); while(num!=0) { r=num%10; sum=sum+r; num=num/10; } printf("Sum of individual digits is %d",sum); return 0; }
  37. C program to display the reverse of a supplied number.
    38. #include <stdio.h> int main() { int num,a,r,sum=0; printf("Enter any number "); scanf("%d",&num); a=num; while(num!=0) { r=num%10; sum=sum*10+r; num=num/10; } printf("Reverse of %d is %d",a,sum); return 0; }
  38. C program to test whether the supplied number is Palindrome number or not.
    39. Hint: A word, phrase, or sequence that reads the same backwards as forwards is called Palindrome. Example : 121 , 101 etc
    #include <stdio.h> int main() { int num,a,r,sum=0; printf("Enter any number "); scanf("%d",&num); a=num; while(num!=0) { r=num%10; sum=sum*10+r; num=num/10; } if(a==sum) printf(" %d is Palindrome Number",a); else printf(" %d is not Palindrome Number",a); return 0; }
  39. C program to check whether the given number is Armstrong or not.
    40. An Armstrong number is a number which equal to the sum of the cubes of its individual digits. For example: 153 is an Armstrong number as- 153=(1)3+(5)3+(3)3=1+125+27=153
    #include <stdio.h> int main() { int num,a,r,sum=0; printf("Enter any number"); scanf("%d",&num); a=num; while(num!=0) { r=num%10; sum=sum+r*r*r; num=num/10; } if(a==sum) printf("%d is Armstrong number",a); else printf("%d is not Armstrong number",a); return 0; }

    1
    2 2
