There are two types of parameters passing conventions in c:
pascal: In this style function name should (not necessary ) in the uppercase .First parameter of function call is passed to the first parameter of function definition and so on.
cdecl: In this style function name can be both in the upper case or lower case. First parameter of function call is passed to the last parameter of function definition. It is default parameter passing convention.
Please get below Examples to get more clarification:
#include<stdio.h>
int main(){
static int a=25;
void cdecl conv1() ;
void pascal conv2();
conv1(a);
conv2(a);
return 0;
}
void cdecl conv1(int a,int b){
printf("%d %d",a,b);
}
void pascal conv2(int a,int b){
printf("\n%d %d",a,b);
}
Output: 25 0
0 25
