I am relatively new to C. My program is supposed to fill in the array with random numbers and i have to find the max and min using 1 function. The program works fine up until the point i have to return the values my 2 pointers get from the function. When i go to print them the porgram stop working and exits with the return value of 3221225477. I have been trying to fix this for 3 hours and i am going INSANE. Please help in any way you can i would really apreciate it.
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
void MaxMin(int size, int *B, int *Max, int *Min);
int main(int argc, char *argv[])
{
int N, i,*A,*MAX,*MIN;
srand(time(NULL));
/*Making sure the user enters a proper value for the array*/
do
{
printf("Give the number of spaces in the Array
");
scanf("%d",&N);
}
while(N<1);
A = (int *) malloc(N*(sizeof(N)));
/*Giving random numbers to the array and printing them so i can make sure my code is finding the max min*/
for(i=0;i<N;i++)
{
A[i]=rand()%100;
printf("
%d
",A[i]);
}
/*Calling my void function so that the pointers MAX and MIN have a value assigned to them */
MaxMin(N, A, MAX, MIN);
/*Printing them*/
printf("
Max = %d
Min = %d",*MAX,*MIN);
free(A);
return 0;
}
/*The function*/
void MaxMin(int size, int *B, int *Max, int *Min)
{
/*using 2 temporary ints to get max min cause pointers and arrays confuse me*/
int max=B[0],min=B[0],i;
for(i=1;i<size;i++)
{
if(max<B[i])
{
max = B[i];
}
if(min>B[i])
{
min = B[i];
}
}
/*These have the proper value last i chekced */
Max = &max;
Min = &min;
}
(edit) SOLUTION Ty so much for the help !
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
void MaxMin(int size, int *B, int *Max, int *Min);
int main(int argc, char *argv[])
{
int N, i,*A,MAX ,MIN ;
srand(time(NULL));
/*Making sure the user enters a proper value for the array*/
do
{
printf("Give the number of spaces in the Array
");
scanf("%d",&N);
}
while(N<1);
A = (int *) malloc(N*(sizeof(int)));
/*Giving random numbers to the array and printing them so i can make sure my code is finding the max min*/
for(i=0;i<N;i++)
{
A[i]=rand()%100;
printf("
%d
",A[i]);
}
/*Calling my void function so that the pointers MAX and MIN have a value assigned to them */
MaxMin(N, A, &MAX, &MIN);
/*Printing them*/
printf("
Max = %d
Min = %d",MAX,MIN);
free(A);
return 0;
}
/*The function*/
void MaxMin(int size, int *B, int *Max, int *Min)
{
*Max=B[0];
*Min=B[0];
int i;
for(i=1;i<size;i++)
{
if(*Max<B[i])
{
*Max = B[i];
}
if(*Min>B[i])
{
*Min = B[i];
}
}
}
