Question

#include<stdio.h>
struct x{
int i;
char ch;
}y();

void main()
{ run();
}
void run()
{ int c;
struct x info;
char symbol[9]={'1','2','3','4','5','6','7','8','9'};
display(symbol);
info=y(symbol,c);
symbol[info.i]=info.ch;
display(symbol);
}
struct x y(char sym[9],int c){
char value[1];
struct x info;
in:
if(c%2==0){
printf("\nEnter your choice: X");
}else{printf("\nEnter your choice: O");

}scanf("%s",value);
for(i=0;i<9;i++){
if (*value==sym[i]){
info.i=i;
if (c%2==0)
info.ch='X';
else

break;
}else{
info.i=-1;
info.ch="";
}

}if(info.i==-1){
printf("\nInput Invalid");
