Pointer to pointer array

Question

I wonder if in the code below (the variable 'p') is a Pointer to an Array of Pointers ?

#include <stdio.h>

int main () {

double valor = 7;
double *balance[5] = {&valor, &valor, &valor, &valor, &valor};
double **p;

p = balance;

return 0;
}

Answer 1

The answer to your question is yes, when you did double **p you have created a variable which is pointer of a pointer of double. When accessing the value of P, use *p[índice].

#include <stdio.h>
 
int main (void)
{
    double valor = 7.0;
    double *balance[5] = {&valor, &valor, &valor, &valor, &valor};
    double **p;
 
    p = balance;
    int i=0;
    for(i=0;i<5;i++)
        printf("%lf\n",*p[i]);
    return 0;
}
