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); }

REVERSE NUMBER

Reverse number #include < stdio.h > int main() { int n, reverse = 0; printf("Enter a number to reverse\n"); scanf("%d",&n); while (n != 0) { reverse = reverse * 10; reverse = reverse + n%10; n = n/10; } /*taking unit place digit of no and moving to reverse Dividing the no to discard unit place digit*/ printf("Reverse of entered number is = %d\n", reverse); return 0; }

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; }
