how to dynamically add to a int pointer array code example
Example: c infiite array
int main(int argc, char *argv[])
{
int i;
double* p; // We uses this reference variable to access
// dynamically created array elements
p = calloc(10, sizeof(double) ); // Make double array of 10 elements
for ( i = 0; i < 10; i++ )
*(p + i) = i; // put value i in array element i
for ( i = 0; i < 10; i++ )
printf("*(p + %d) = %lf\n", i, *(p+i) );
free(p); // Un-reserve the first array
putchar('\n');
p = calloc(4, sizeof(double) ); // Make a NEW double array of 4 elements
// ***** Notice that the array size has CHANGED !!! ****
for ( i = 0; i < 4; i++ )
*(p + i) = i*i; // put value i*i in array element i
for ( i = 0; i < 4; i++ )
printf("*(p + %d) = %lf\n", i, *(p+i) );
free(p); // Un-reserve the second array
}
