1. What will be the output of the program? #include<stdio.h> #define PRINT(i) printf("%d,",i) int main() { int x=2, y=3, z=4; PRINT(x); PRINT(y); PRINT(z); return 0; }

The macro PRINT(i) print("%d,", i); prints the given variable value in an integer format. Step 1: int x=2, y=3, z=4; The variable x, y, z are declared as an integer type and initialized to 2, 3, 4 respectively. Step 2: PRINT(x); becomes printf("%d,",x). Hence it prints '2'. Step 3: PRINT(y); becomes printf("%d,",y). Hence it prints '3'. Step 4: PRINT(z); becomes printf("%d,",z). Hence it prints '4'. Hence the output of the program is 2, 3, 4.
