How do i assign a random number to a int or a var?

Question

I was trying to assign random numbers to an int and it refused to work idk if I’m messing up the = and the == but I’m a doing something wrong. It works when I cout the random number but it doesn’t save when I assign it to a value

Answer 1

Since you use cout, I assume your question is for C++.
It works just like every other assignment:
int var = rand(); ,
where var will be a random value between 0 and, by default, 32767 I think.
You can limit the range using
int var = x + rand() % y; ,
where x is the lowest possible number and y the upper limit (not included in range though).
Then you can use var in your code, just make sure you included <cstdlib> for the rand()-prototype and <ctime> if you seed with a time value.

Answer 2

Thats because
1) you use a wrong operator. One = is enough when assigning values.
2) In an assignment, there are lvalues (left side of =) and rvalues (right side of =). The value you are trying to assign has to be the rvalue!
In conclusion, lines 20 - 26 should look like
a = rand();
