Your program must define and call a function. swapvalues returns the two values in swapped order.
void swapvalues(int* userval1, int* userval2)
#include
/* define your function here */
int main(void) {
/* type your code here. your code must call the function. */
return 0;
}

no. when the asker posts the question they can make a question worth what ever they think is a fair price. although it must be within the limit of the points they currently own. 5 is the minimum number of points a question can be worth. if a question is complicated or has lots of parts to it, it is better to make it worth more because more people will be more willing to answer.

hope this !
