Question 1: Consider the code:

Please give a good explaination of the question and explainig the conetp of pass by reference. Thank you.

int main ( ) {

int n=2;

int m=1;

if (1==1) {

int n ;

n = foo (m, n ) ;

return ( n )

}

int foo (int m, int n ) {

n++; m++;

return (m+n )

}

a. What are m and n after the above code executes (assuming youve added appropriate prototypes, headers, etc.)?

b. Repeat if foos second argument is passed by reference.

c. Repeat if foos first argument is passed by reference.

d. Identify those positions in the program where you can modify the value of the n declared at the top of main.
