Why this code has erro

Question

#include <stdio.h>

int factorial (int n){
if (n == 1 || n == 0)
{
return 1;
}
eles {
return n*factorial(n-1);
}

}
int main() {
int a;
printf ("Pavel");
scanf("%d",a);
printf ("Anik %d is %d\n",a,factorial (a));
return 0;
}

Answer 1

#include <stdio.h>

int factorial (int n){
if (n == 1 || n == 0)
{
return 1;
}
else{//here it said eles
return n*factorial(n-1);
}

}
int main() {
int a;
printf ("Pavel");
scanf("%d",&a); //& ampersand was missing
printf ("Anik %d is %d\n",a,factorial (a));

//printf("%p",&a); /*display memory address of a*/

return 0;
}

/*when using scanf you need the memory address of the variable, not the variable itself, that is obtained by prepending "&"*/

Answer 2

Bong Rush Gaming YT It has a misspelling of the keyword, else.
