Problem with simple function in C

I am new in C and I have problem with compiling this code.

#include <stdio.h>

void suma( int a, int b, int wynik)
{
    wynik=0;
    printf("a=\n");
    scanf("%d",&a);
    printf("b=\n");
    scanf("%d",&b);开发者_JAVA百科
    wynik=a+b;
    printf("wynik = %d",&wynik);
}


int main()
{
    suma(int a, int b, int wynik);
}

I don't know why but compiler tells me that 2 argument has type int * insted of int. I dont' know what does it mean and where I made mistake.

Change

printf("wynik = %d",&wynik);

to

printf("wynik = %d",wynik);

Otherwise you'll be printing the address of wynik as an integer.

Also the way you call suma makes no sense.

change printf("wynik = %d",&wynik); to printf("wynik = %d",wynik);

and also you don't seem to need the arguments of suma.

Try this:

void suma()
{
    int a,b,wynik;
    wynik=0;
    printf("a=\n");
    scanf("%d",&a);
    printf("b=\n");
    scanf("%d",&b);
    wynik=a+b;
    printf("wynik = %d",wynik);
}


int main()
{
    suma();
}
