Void multiplication1 ()
{
Int the product;
Int multiplication1A=rand () % 10;
Int multiplication1B=rand () % 10;//set up two random number
The product=multiplication1A * multiplication1B;
Printf (" % d % d *=? The \ n ", multiplication1A, multiplication1B);//print issue
}


If I want to get the product value, how to do

CodePudding user response:

Int multiplication1 ()

}

CodePudding user response:

 int multiplication1 () 
{
Int the product; 
Int multiplication1A=rand () % 10; 
Int multiplication1B=rand () % 10;//set up two random number 
The product=multiplication1A * multiplication1B; 
Printf (" % d % d *=? The \ n ", multiplication1A, multiplication1B);//print issue 
Return the producet; 
} 

Method 1

 void multiplication1 (int * output) 
{
Int the product; 
Int multiplication1A=rand () % 10; 
Int multiplication1B=rand () % 10;//set up two random number 
The product=multiplication1A * multiplication1B; 
Printf (" % d % d *=? The \ n ", multiplication1A, multiplication1B);//print issue 
* the output=the product; 
} 

Method 2
Pay attention to method 2 need to pass the address of a variable of type int,
