C Programming Tutorial 19, Arrays pt.4

[gpps]

awesome videos! i like to pause the video once you explain the idea, and then try and solve it myself when possible

[iTzAdamX]

Yeah you're right. The format %s can only be used when printing out an array of characters, it's only for use with strings.

[Stanislavs]

More efficient version. Less lines, loops, variables :)

int nums[] = {1, 2, 3, 4, 5};
int i;
    for(i=4; i>-1; i--)
    printf("%d", nums[i]);
return 0;

The 'int i' can be fitted into the 'for' sequence too.  My compiler doesn't recognize it that way though.

we can also write this code instead of two arrays
#include <stdio.h>
#include <stdlib.h>

int main()
{
int numbers[] ={1, 2,3,4,5};
for(int i=4;i>=0;i=i-1)
{
printf("%i\n", numbers[i]);
}
return 0;
}

Hay, Adam do you think you could do some videos on Frequency and Histogram's? And Selection Sorting like bubble, insertion, ext...?

[SuperSamsosa]

Question !

In lines 10 and 11 instead of using a for Loop cant i just type :

printf ("%s", reversed);

or is it nor possible because a string can only consist of char values and not of integers or floats for examples.

[bobicemj]

keep up the great videos! also, do you know c++ or java?

[Torcika]

how do you code for the elements to appear in a triangular shape on the screen?

[djleisheng]

[4 - i] means this:

 i = 0 so 4 - 0 = 4
 i = 1 so 4 - 1 = 3
 i = 2 so 4 - 2 = 2
 i = 3 so 4 - 3 = 1
 i = 4 so 4 - 4 = 0

Adam, I have a question about arrays and C. Do you have a website or email address so I can run some stuff by you? Sorry if your too busy. Keep up the good work.

[OneTimWhatley]

so that's pretty much it for this tutorial, so see you guys.

[YTHandle]

Hmm. Use the swapping Techniac. Where if i is bigger then i+1 swap

[m.mohammad]

what does this mean 4 - i and do you know anything about sprintf()

[lsenthil]

I tried this program, for me the last element is getting printed twice
