doin't compile */*/*/*------>

[enjoy]

help me to compile these code please

#include "stdio.h"
#include "string.h"
#define n 100
void e(int i,int *t[i],int *a[i])
{
*t[i]=1;
*a[i]=1;

}
void main()
{
	int k=1;
    int a[n],b[n];
	e(k,&a[k],&b[k]);
	printf("a[k]=%i et b[k]=%i",a[k],b[k]);
}

>void e(int i,int *t[i],int *a[i])
void e(int i, int *t[], int *a[] )

>void main()
Bzzt. Wrong. int main( )

>e(k,&a[k],&b[k])
e(k,&a,&b)

>printf("a[k]=%i et b[k]=%i",a[k],b[k]);
printf("a[k]=%d et b[k]=%d",a[k],b[k]);

why has it become popular to do this

#include "stdio.h"
#include "string.h"

It should be

#include <stdio.h>
#include <string.h>

There is a difference, one looks in the current directory or one specified by command line args to the compiler before looking in the system include directories! So you could have a version of stdio.h in the current directory and it could be different than the one in /usr/include!

It's just one of many persistent mistakes in enjoy's code.

[Stack Overflow]

Does this compile?

#include <stdio.h>
#include <string.h>

void e(int i,int *t,int *a) {
	*t = 1;
	*a = 1;
}

int main() {
	int k = 1;
    int a[100], b[100];

	e(k, &a[k], &b[k]);
	printf("a[k]=%i et b[k]=%i", a[k], b[k]);

	return 0;
}

Fix #1: *a[i] amd void e(int i,int *t,int *a)

Fix #2: *t[i]=1; and *a[i]=1 are not needed because you already defined your array calling the function so it can be changed to: *t = 1; and *a = 1;

Fix #3: int a[n]; will not work, it needs a number instead of a variable constant so instead of that use int a[100];

Fix #4: Use int main() instead, void main() isn't to recommended by programmers.


Hope this helps,

For the printf statement, you need %d instead of %i. His array declaration was valid because he #defines n at the top of his code.

thanks all my code is compilling now ........ (:d

[linuxdude]

%d and %i are interchangable in printf you should know that XSquared.

i approve these linuxdude

I should, but I didn't. Until now. Thanks.

Is this like those Presidential ads they keep running?
