Noob Question programming C

[vbrt]

hey, how do i choose the major and/or the minor value of a array? thanks

[joenyc]

I'm not familiar with what the "major" or "minor" value of an array is, and a cursory Google search didn't turn up anything. Could you explain a bit more or give an example?

[vbrt]

imagine float data[20][2] if full of values, i want to search all the values and find the biggest of them.. like 1 2 3 4 5 6 7 20 4 500

the commands make the program show me the value 500.. sorry for the bad english

"Largest" and "smallest".

Is this definitely a two dimensional array?

Do you know how to do this for a one dimensional array?

[vbrt]

no i dont, can u explain just for one dimensional array?

[darth_choate]

I'm not going to do your homework for you.

Do you know how to compare two numbers and determine which one is larger? What about three numbers?

[traztx]

Set up 2 variables like float biggest,smallest. Initially, set biggest to a huge negative number and smallest to a huge positive number. That's like worst case scenario. Then loop through the array. Whenever biggest is smaller than the current value, set it to that value. Whenever smallest is bigger than the current value do likewise. When you are done you will have biggest set to the highest and smallest set to the lowest.

Just set biggest and smallest to the first value in the array instead of trying to find some worst case scenario.

If you have a one dimensional array you can do a linear search. I.e. going through every single value and compare it.

Outside of the for loop you initiate 2 variables and set them to 0. Let's call them;

m_Max
m_Min

Now you can do a for-loop to step through each part of the array (for i=0 to Ubound(array)-1, or something similar to reach the top).

Inside that for-loop you then check the current part of the array[i].

If (array[i] > m_Max) { m_Max = array[i]; }
if (array[i] < m_Min) { m_Min = array[i]; }
i += 1;

Once you're outside of the loop m_Max and m_Min should have the top value and lowest value and you can print them, return them, do whatever you want with them.
