What is the output of the following C program?Cmain{ int a,b; a=77; b=40; a+=b; printf("a= %d", a);}.
Correct answer: C. a=117
- A. a=77
- B. b=40
- C. a=117
- D. Compile time error
Explanation
int a,b;: This line declares two integer variables a and b.a=77;: This line assigns the value 77 to variable a.b=40;: This line assigns the value 40 to variable b.a+=b;: This line is an assignment expression. The += operator is a shorthand for a = a + b. So, in this line, the value of b (which is 40) is added to the current value of a (which is 77), and the result (117) is stored back into variable a.printf("a= %d", a);: This line prints the value of variable a to the console. Since a now holds the value 117, the output will be:a= 117
