Question

Suppose an integer array A has been declared and initialized for you, and you don't know the length. Write a code fragment to input an integer from the console, search the array, and output "YES" if the input value was found in the array, and "NO" if not. Instructor's notes: Use the "sizeof" pattern we learned in class to compute the length N of the array. Declare all variables you need, including N. HINT: the solution is more difficult than finding the largest / smallest element, so you need to take a slightly different approach in this case. A simple if-then-else inside the loop will not work...

Explanation / Answer

#include<iostream>
#include<cmath>

using namespace std;

int main()

{

int A[]={3,4,5,6,3,55,43,32,3433,34};

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

int num;

int found=0;

cout<<"Enter value to search for: ";

cin>>num;

for(int i=0;i<N;i++){

if(A[i]==target){

found=1;

break;

}

}

if(found==1)

cout<<"YES";

else

cout<<"NO";

return 0;

}
