Answer 1

You have to declare the function before the point you are gonna call it.
test();

int main()
{

printf("I am going inside test function now\n");
test();
printf("\nNow I am back from test function\n");
system("pause");
}

test()
{
int a,b;
a=1;
b=a+100;
printf("a is %d and b is %d",a,b);
}

Answer 2

First of all there are a lot of errors
But if you did not consider that then the answer is :
I am going inside test function now
a is 1 and b is 101
Now I am back from test function
