Ask bosses what was going on, what should change, thank you very much
Code:
#include
Int * find (int * p, int l, int x) {
Int a [100], I;
For (p=a; pIf (* p==x);
return p;
If (* p!=x)
The return p - l - 1;
}
}
Int main () {
Int a [5], * p, I, x, l, s;
Printf (" a: ");
For (p=a; pThe scanf (" % d ", p);
Printf (" x, ");
The scanf (" % d ", & amp; X);
S=find (p, l, x) - p;
Printf (" % d \ n ", s);
return 0;
}
