Gate2019 cs Q28

28Consider the following C program:

int jumble(int x, int y){
x=2*x+y;
return x;
}
int main(){
int x=2, y=5;
y=jumble(y,x);
x=jumble(y,x);
printf(“%d \n”, x);
return 0;
}
The value printed by the program is _______.

Note – Numerical Type question

Option : A
Explanation :
Given, “for” loop will run from i=0 to 4.
i = 0
sum = 0+ 10 – 10 = 0
i = 1
sum = 0 + 9 – 8 = 1
i = 2
sum = 1 + 8 – 6 = 3
i = 3
sum = 3 + 7 – 4 = 6
i = 4
sum = 6 + 6 – 2 = 10
Now, loop terminate and value of sum (i.e., 10) will be printed.
So, The output of above C program is 10.
