error: invalid type argument of ‘unary *’ (have ‘int’)

Question

I have a C Program:

#include 
int main(){
  int b = 10;             //assign the integer 10 to variable \'b\'

  int *a;                 //dec         


        

Answer 1

Since c is holding the address of an integer pointer, its type should be int**:

int **c;
c = &a;

The entire program becomes:

#include                                                               
int main(){
    int b=10;
    int *a;
    a=&b;
    int **c;
    c=&a;
    printf("%d",(**c));   //successfully prints 10
    return 0;
}
