#include<stdio.h>
int areaOfRectangle(int,int);
int perimeter(int,int);
int main()
{
int l,b;
scanf(" %d %d",&l,&b);
printf("%d %d %d %d",l,b,areaOfRectangle(l,b),perimeter(l,b));
return 0;
}
int areaOfRectangle(int a,int b)
{
int area;
area=a*b;
return area;
}
int perimeter(int c,int d)
{
int meter;
meter=2(c+d);
return meter;
}
why this error:called object is not a function or function pointer at line: meter=2(c+d)?
Also, can I use the same variable a,b to pass in perimeter function?
Your code meter=2(c+d);should be changes as meter=2*(c+d); You can use the same variable a,b to pass in perimeter function, A parameter is just a local variable.
