1)
main()
{
int i=10;
void pascal f(int,int,int);
f(i++,i++,i++);
printf(” %d”,i);
}
void pascal f(integer :i,integer:j,integer :k)
{
write(i,j,k);
}
Answer:
Compiler error: unknown type integer
Compiler error: undeclared function write
Explanation:
**Pascal keyword doesn’t mean that pascal code can be used. It means that
the function follows Pascal argument passing mechanism in calling the functions.

2)
**
void pascal f(int i,int j,int k)
{
printf(“%d %d %d”,i, j, k);
}
void cdecl f(int i,int j,int k)
{
printf(“%d %d %d”,i, j, k);
}
main()
{
int i=10;
f(i++,i++,i++);
printf(” %d\n”,i);
i=10;
f(i++,i++,i++);
printf(” %d”,i);
}
Answer:
10 11 12 13
12 11 10 13
Explanation:
Pascal argument passing mechanism forces the arguments to be called
from left to right. cdecl is the normal C argument passing mechanism where the
arguments are passed from right to left.
