It is just as you use other data types.
Consider this case of linear search in array

int arr[4]={1,2,4,11};
bool found=false;
int key=4;
//Now check if 4 is present in the array
for(int i=0;i<4;i++)
{
if(arr[i]==key)
{
found=true;
break;
}
}
if(found) cout<<"Key is present in the array";
else cout<<"Key not present";
