Answer 1

Just as you will in a C program:

-(void) myVoidMethod {
    BOOL res;
    res = test();
}

Don't forget to declare / include relevant header (again, just like in a C program).

Also, as daknøk mentioned, Objective-C is a strict superset of C, so what works with C - works with Objective-C.

Answer 2

you can call c functions from object-c function in the fallowing way...

-(void)viewDidLoad
{
  // calling the c function from objective-c function 

    someFunctionName();
}

this is my object-c function

void someFunctionName()
{
  // write logic what you want in this function...

  int a ,b;
  a=10;
  b=20
 printf("A value is %d \n B value is %d",a,b);


}

this is my c function ...
