Q1. Write a C program to calculate xy without using standard library function.

[15 Marks]

#include<stdio.h>
#include<conio.h>
void main()
{
 int x,y,i,r=1,t;
 printf("Enter a number:");
 scanf("%d",&x);
 printf("Enter the power:");
 scanf("%d",&y);
 for(i=1;i<=y;i++)
 {
  t=x;
  r=r*t;
 }
 printf("Result:%d",r);
 getch();
}

Q2. Write a program to display union and intersection of two 1D array. [25 Marks]

#include<stdio.h> 

int printIntersection(int arr1[], int arr2[], int m, int n) 

{ 

  int i = 0, j = 0; 

  while (i < m && j < n) 

  { 

    if (arr1[i] < arr2[j]) 

      i++; 

    else if (arr2[j] < arr1[i]) 

      j++; 

    else /* if arr1[i] == arr2[j] */

    { 

      printf(" %d ", arr2[j++]); 

      i++; 

    } 

  } 

} 

  int main() 

{ 

  int arr1[] = {1, 2, 4, 5, 6}; 

  int arr2[] = {2, 3, 5, 7}; 

  int m = sizeof(arr1)/sizeof(arr1[0]); 

  int n = sizeof(arr2)/sizeof(arr2[0]); 

  printIntersection(arr1, arr2, m, n); 

  getchar(); 

  return 0; 

}
