1st 2 time a value is increment then return, but why show output 23? Any tricks inside here?

Question

Int main(){
Int a=1;
Printf("%d",++a);
Func();
Printf("%d",++a);
Return 0;
}
Void main(){
Int a= 10;
Return 1;
}

Answer 1

Your code have errors lot.. Look again..

First printf prints ++a value which is 2,and now a = 2
Next printf prints in same way as 3, now a = 3 so output is 23.

May you mean corrected code is :
1st 2 time a value is increment then return, but why show output 23? Any tricks inside here?

int main(){
int a=1;
Printf("%d",++a);
Func();
printf("%d",++a);
return 0;
}
void Func(){
intt a= 10;
}

This function Func has no effect on code..
