you can add a "break". Since there are two statements in the "if", you'll have
to enclose them in a block.
Another variant: you can put the "FOUND" output statement in the
if-statement as well. You will still need a "break" and a boolean
variable to indicate that the number has been found.
That is, the code may look like this:
bool located=false;
for(int i=0; i < SIZE; i++)
if(myarray[i] == number){
located = true;
cout << "FOUND";
break;
}
if(!located)
cout << "NOT FOUND";
