GENERATE ARMSTRONG NUMBER

Generate armstrong number

#include < stdio.h >

int main()
{
  int r;
  long number = 0, c, sum = 0, temp;

  printf("Enter an integer upto which you want to find armstrong numbers\n");
  scanf("%ld",&number);

  printf("Following armstrong numbers are found from 1 to %ld\n",number);

/*if sum of cubes of each digit in a number is same as the number then it is called as armstrong no.*/
  for( c = 1 ; c < = number ; c++ )
  {
  temp = c;
  while( temp != 0 )
  {
  r = temp%10;
  sum = sum + r*r*r;
  temp = temp/10;
/*taking unit place digits cube and adding into sum*/
  }
  if ( c == sum )
  printf("%ld\n", c);
/*If no is Armstrong no then print*/
  sum = 0;
  }

  return 0;
}

GREATEST OF 3 NUMBERS

Greatest of 3 numbers #include < stdio.h > void main() { int a,b,c; printf("enter any three numbers:\n"); scanf("%d%d%d",&a, &b, &c); if(a>b&&a>c) /*if a is greater than b & c*/ printf("greatest number is: %d",a); else if(b>c) /*if not a then if b is greater than c*/ printf("greatest number is: %d",b); else /*if a & b are not greater*/ printf("greatest number is: %d",c); }

SWAPPING TWO NUMBERS

Swapping two numbers #include < stdio.h > int main() {   int x, y, temp;   printf("Enter the value of x and y\n");   scanf("%d%d", &x, &y);   printf("Before Swapping\nx = %d\ny = %d\n",x,y);   temp = x;   x = y;   y = temp; /*using temp to swap storing x to temp and y to x then moving temp to y*/   printf("After Swapping\nx = %d\ny = %d\n",x,y);   return 0; }

CALCULATE PERCENTAGE

Calculate percentage #include < stdio.h > void main() { int s1, s2, s3, s4, s5, sum, total = 500; float per; printf("\nEnter marks of 5 subjects : "); scanf("%d %d %d %d %d", &s1, &s2, &s3, &s4, &s5); sum = s1 + s2 + s3 + s4 + s5; printf("\nSum : %d", sum); per = (sum * 100)/500; /* percentage formula*/ printf("\nPercentage : %f", per); }
