To find biggest of n numbers ?

[Tarun Jha]

do you mean inside he inner for loop, to print value of i ?

Most of that code is redundant, all you need is something like:

int num = -1, largest = 0;

do{
printf("Enter an integer, 0 to exit:\n");

scanf("%d", &num);
if (num > largest)
    largest = num;

}while(num != 0);
printf("%d is the biggest number", largest);

I know that method but i need to know what is wrong with the one i am working with.

Start with the hint that jschell gave, look at that line of code and see what it is doing if anything, or better yet step though each line of code with a debugger.

The problem is obvious

if(i != j)
num[i] > num[j];
else
break;

Start with i=0 j = 0 what does the break do ... i==j doesn't it so it will call the break .. single step debug and watch :-)

Your second loop makes no sense as you are using two index varaibles when you only need one, and you never compare the values to see which is largest, or keep a note of the largest value you have found so far.

ohh! :omg: Thank you. but the code written below only works some time.. :sigh:

#include
#include

int main(){

int num\[50\], i=0, j, count =0;
int k, b;

printf("Enter 0 to exit entering integers.\\n\\nEnter your integers:\\n");

do{

	scanf("%d", &num\[i\]);
	i++;
	count++;

}while(num\[i-1\]!=0);

for(k=0; k<=count-2; k++){

    for(j=0; j<=count-2; j++){

        if(k != j){
            num\[k\] > num\[j\];
            b = k;
        	//printf("%d", num\[k\]);
        	continue;
			}
        else
            break;
    }
    //printf("%d is the biggest number \\n", num\[k\]);
}

printf("%d is the biggest number", num\[b\]);

return 0;

}

Which technically means it does not work. If your algorithm is dependent upon its input in order to produce the correct output, it is wrong, period. You should be able to do this entire exercise using pencil and paper before ever committing anything to code. Short of that and you are just guessing (hoping) at best.

Yes, because your code is still wrong, mainly because there is no logic to it. I gave you the answer in a previous comment, which should at least give you an idea of the logic involved in such a simple task.

Print i,j and the array values of each before and after that line.
