Pointer of int

[w4ssup]

I'm having a stroke or some shit but i cant seem to get this working (it been a while since i deal with pointers).
I have a function that takes in a int pointer

void getINPUTandClear(int * something)

I declared my var

int day = -1;
\\or
int * day;
*day= -1;

and I'm trying to pass the point to the function by

getINPUTandClear(&day);
\\or
getINPUTandClear(*day);
\\or 
getINPUTandClear(day);

but all of those wouldn;t work. What's am i doing wrong?

idk much about c++ pointers but shouldn't it be:
void getINPUTandClear(int & something)

Use references wherever possible, use pointers only if you can't avoid them.

Regardless, if you want to use pointers, this should work just fine:

void getINPUTandClear(int* something);

int day = -1;

getINPUTandClear(&day);

or else if you declare day as a pointer:

void getINPUTandClear(int* something);

int* day;
*day = -1;

getINPUTandClear(day);

[Hell_Demon]

or else if you declare day as a pointer:

void getINPUTandClear(int* something);

int* day;
*day = -1;

getINPUTandClear(day);

In both this and OPs example the day pointer is uninitialized.

Correct, overlooked that.

The day pointer will need to be initialized to point to the variable that will be actually modified.

In C:

(U should use prints to understand how things work.)

#include <stdio.h>

double minmaxavg(double array[], int num, double *max,double *min);

double minmaxavg(double array[], int num, double *max,double *min){
	int i;
	double sum =0;
	for(i =0;i< num;i++){
		if(array[i] > *max){
			*max = array[i];
		}
		if(array[i] < *min){
			*min = array[i];
		}
		sum +=array[i];
	}
	return sum;
}

void main(){
	double sum;
	double max =1;
	double min =1;
	double arr[] = {1,3,2,5,4,6,8,7,99,0};
	//double *pArr;
	double *pMax;
	double *pMin;
	//pArr = &arr;
	pMax = &max;
	pMin = &min;
	sum =minmaxavg(arr,10,pMax,pMin);
	printf("sum:%g min:%g max:%g",sum,min,max);
}

I must have overlooked that.
