#include "stdio.h" #define prod(a,b) a*b int main() { int x=3, y=4; printf("%d", prod(x+2, y-1)); return 0; }

---

Explaination

prod(a,b) = a*b
prod(x+2, y-1) = x+2*y-1 = 3+2*4-2 = 3+8-1 = 10
If the programmer really wants to multiply x+2 and y-1, he should have put paranthesis around a and b

Write a program to give the following output for the given input

Input

a1b10

Output

abbbbbbbbbb

Input

b3c6d15

Output

bbbccccccddddddddddddddd

int main() { int (x) = 10; printf("x = %d", x); return 0; }

Explaination

Such declarations are also accepted by C and C++ compilers.

int main() { char x = 'AB'; printf("%c", x); return 0; }

---

Explaination

The program executes with warning. warning is thrown because of initialising multicharacter to a char variable. Therefore, overflow occures and hence B only gets printed.
