What is the output of the following code value of a and valu

What is the output of the following code (value of a and value of b)? void func1(int * p1, int*p2) {int temp; temp = * p1; *p1 = *p2; *p2 = temp;} int main() {int a = 10, b = 20; func1(&a;, &b;); cout

Solution

c)answer:-

output is:

value of a is20
value of b is10

explanation: -

call by reference method is used here...

both variable are swapped in the func1() function, we have passed the reference of current variables, so, they are swapped

d)answer:-

output is:

404141

explanation:-

two pointer variables are created ptr1,ptr2..

both are assigned to a same memory block..

40 value is assigned to *ptr1, means it also assigned to *ptr2

both values of *ptr1 and *ptr2 is 40

ptr1 is printed, means 40 is printed

(*ptr2)++, now *ptr2 is incremented, so its value is now 41, and ptr1 value also 41

now *ptr1,*ptr2 are printed, means 4141 is printed

the output is:

404141
