Detect maximum and minimum value in array

IMO, you would have pinpointed this problem in 1 minute, by using the debugger and single-step your program.
Learning how to use the debugger is well worth the time spent.

You are declaring minimum as a value a[0] before assigning a value to a[0].

hi,

first initialize the value of a[0]

a[0]=0;

second

for ( i= 0 ;i < (arraysize);i++ )

hope now u can run ur programme.

I think so. Loop //for ( i= 0 , i > (arraysize) , i++ ) not has a end point. in fact, this willn't be excuted because conditions is not true

very simple answer is to look at the loop and change > to <
i < arraysize

OMG Look at the accepted answer :doh:
He didnt event point the actual problem in for loop check expression. and there is nothing wrong with setting junk/default value to minimum as it will get updated in loop.

Y u ppl recommending to hardcore values of minimum and maximum to 0 and let it use as it is for checks?
Think what if minimum value set to 0 and actual minimum value in array is 1 :doh:

your actual code should be like this

#include
using namespace std;

int main ()

{	int const arraysize=10;
	int a[arraysize];
	int maximum=0;  
	int minimum=0;  
	int i;
	
	for ( i= 0 , i > (arraysize) , i++ )
	{
		cin>>a[i];

		if (a[i]>=maximum || i==0)
			maximum=a[i];

		if(a[i]<=minimum || i==0)
			minimum=a[i];
	}
	
		cout<<"the maximum of array a is : "<<maximum<<endl;
		cout<<"the minimum of array a is : "<<minimum<<endl;
 
		
return 0;

}
