Write an expression that executes the loop while the user enters a number greater than or equal to 0.

note: these activities may test code with different test values. this activity will perform three tests, with usernum initially 9 and user input of 5, 2, -1, then with usernum initially 0 and user input of -17, then with usernum initially -1. see "how to use zybooks".

also note: if the submitted code has an infinite loop, the system will stop running the code after a few seconds, and report "program end never reached." the system doesn't print the test case that caused the reported message.

#include
using namespace std;

int main() {
int usernum;

usernum = 9;

while (/* your solution goes here */) {
cout < < "body" < < endl;
cin > > usernum;
}
cout < < "done." < < endl;

return 0;
}

Idon understand these and need some ! ?

Write a function called checkfactor that takes two arrays of positive numbers, firstnumberrow and secondnumberrow. checkfactor checks if the first entry in firstnumberrow is divisible by the first entry in secondnumberrow, and performs the same operation on the next array elements until all entries have been checked. all the numbers are positive and the number of entries in the arrays are the same. the function should return the identified divisible numbers in two row arrays named firstdivisible and seconddivisible.restrictions: branches or loops should not be used. the code must use the internal mod and logical functions.hint: the mod function should be used to determine if two numbers are divisible. ex: for num1 and num2 if mod(num1,num2) is 0, then the two numbers are divisible.this is matlab
