Show the output of the following program You must trace the code to show how you reached the answer.
Solution
#include <stdio.h>
int x = 11;
int y = 5;
void my_first_function();
void my_second_function();
int main()
{
int y;Â Â //y is declared local here.
y = x;Â Â //The value of x i.e., 11(global variable) is assigned to y.
x++;Â Â Â Â Â //x value i.e., 11 is increased to 12.
y++;Â Â Â Â Â //y(local) value i.e., 11 is increased to 12.
for(int i = 0; i < 2; i++)Â Â //This loop runs for 2 times, i.e., for values of 0, 1.
{
my_first_function();Â Â //When called for the first time.
my_second_function();
}
return 0;
}
void my_first_function()
{
printf(\"The value of x+y in my_first_function() is %d\ \", x+y);Â Â //The string is printed with values, 12 + 5 = 17.
//The second time the function is called, the string is printed with values, 99 + 5 = 104.
}
void my_second_function()
{
x = 99;Â Â Â Â Â //The global variable x is updated to 99.
printf(\"The value of x in my_second_function() is %d\ \", x);Â Â //Now the x value is printed as 99.
//Second time this function is called, again it will print the same x value of 99.
}
//So, the values to be printed are:
//The value of x+y in my_first_function() is 17
//The value of x in my_second_function() is 99
//The value of x+y in my_first_function() is 104
