I would like to know if in the code below (the variable 'p') is a Pointer to a Pointer Array?

#include <stdio.h>

int main () {

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

p = balance;

return 0;
}

c c++

The answer to your question is yes, when you did double **p you created a variable that is a pointer to a double pointer. 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;
}
