Solution 1

firstly you have printf spelt with a 1 and that would not compile.

Also remove the ' after the scanf line in the first loop as this would also make it not compile.

Your algorithm is however sound.

Try using following code

C#

#include <stdio.h>
#define arr_size 5
void main(void)
{
    float numbers[arr_size] ;
    int counter;
    printf("Input five numbers: \n");
    for (counter = 0; counter < arr_size; ++counter)
        {
            printf("%i?",counter + 1);
            scanf("%f", &numbers[counter]);
        }
    printf("Here they are:");
    for (counter = 4; counter >= 0; --counter)
    printf(" %g",numbers[counter]);
}

i correct the error already, the the program still cannot run

Guyverthree 16-Apr-11 16:59pm

i think the problem was conio.h not having clrscr() ni it.

I ahve changed it for antoher function that does the same thing from cstdlib

LloydA111 16-Apr-11 16:55pm

Why can it still not run?

Jayfam 16-Apr-11 17:03pm

it showing me the error fatal error: cstdlib: No such file or directory

Guyverthree 16-Apr-11 17:06pm

can you just remove the lib and the system("cls"); functions and compile and run the code then ???

Jayfam 16-Apr-11 17:07pm

i use back my coding and just delete the clrscr(); and it finally run already. Thanks for the help

Jayfam 16-Apr-11 17:18pm

may i know if my output want showing from the begginig like 235 256.23 458 265.12 5 instead of 5 265.12 458 256.23 235
May i know how to do that?

just make the counter variable start from 0 and increment from there until you get to the size of the array (in your last for loop)

Jayfam 17-Apr-11 0:57am

for (counter = 0; counter >= 5; ++counter) like that?
