Re: [Dev-C++] Help me.... strange char functions on MinGW

[Eric <eri...@wo...>]

rats!!


I forgot to tell you I changed
printf("%s", strset("TEST, TEST", 'c') );

to
printf("%s", "TEST, TEST", 'c' );


that is why I thought "there is bound to be a question two"

yes well I got a "this program has performed an illegal operation and will
shut down"

untill I changed
main()
to
int main()
in theory it should go
int main(int argc, char *argv[])
with a return 0; or maybe something else at the end of the main function

the group looks forward to question two on this project



try this


#include <stdio.h>
#include <cstdlib>
#include <iostream>
char *strset(char *s, char ch);


int main()
{
printf("%s", "TEST, TEST", 'c' );
getchar();
    system("PAUSE");
    return EXIT_SUCCESS;
}
char *strset(char *s, char ch)
{
int i;
for(i = 0; s[i]; i++)
s[i] = ch;
return s;
}


If you are going to do HTML EMail, do it with class

Hi All.

I'm learning C with Dev-C++ and MinGW and a wrote such function like this:

#include <stdio.h>

char *strset(char *s, char ch);

main()
{

printf("%s", strset("TEST, TEST", 'c') );
getchar();

}

char *strset(char *s, char ch)
{

int i;

for(i = 0; s[i]; i++)

s[i] = ch;


return s;

}

that would have to fill the string argument with the char ('c') and print
it.

string: "TEST, TEST"
result: "**************"

But, I have a Access Violation, and program crashes.

I've tried to compile in LCCWin32 and runs fine.
Then, I've tried, again, to compile in mingw and ran on MSYS, suprise....
works fine too.

But in a DOS shell, the same mingw compiled program gives me a Access
Violation... Why!!!!????

Please Help...
