MIN function

[Masifrz]

i don't know c has builtin minimum function or not. but i want to write a function which will find minimum number in a integer array.
please hint me i want to use it in a code.

Let's say you have array that contains integers. You define integer called min for example and you put first value of this array into min (min=array[0]). Next thing you have to do is using for loop, to find out if there's any number, that is smaller than value from array[0]. If you find one, you put its value to min variable. In the end, you print min. That's all.

Thanks dear. i have finally do it.
int minimum(int l[], int size) //This function return minimum number in integer array
{
int i,min;
min=0;
for(i=0;i<size;i++) //for loop execute list item time
{

if(l[i]<l[min]) //check array i index element less than array min index element which is zero in first iteration
{
min=l[i]; //if above condition true than array i index element replace array min index element because it is minimum than previous than now it will campare to other remainig items
}
}
return min;
}

if(l[i]<l[min]) min=l[i]
You have a problem; in the first code segment it seems min represents the minimum element number, and in the second it is representing the minimum value. You should just assign i to min instead.

@Zhuge, i think that min=l[i] is correct, but min=0 is not. It should be replaced by min=l[0] and then for loop should start from i=1.

@Masifrz, what if all elements of this array are smaller than zero? That's the reason, why min should be initialized by l[0].

@mtweeman: If you want to do it that way, you'll also want to change the if statement to use min instead of l[min]

[mtweeman]

@Zhuge, I overlooked this. You're absolutely right.

int minimum(int array[], int size) {
    int min = array[0];
    for (int i = 0; i < size; i++) {
        if (array[i] < min) min = array[i];
    }
    return min;
}

That should do it.

Oh, by the way, next time please wrap your code in [code ] [/code ] tags... Without the space in the tags of course. And use proper indentation if possible... Both make it easier to read and cleaner in the post.
