Hello,

I am working on migration of code from 4.2 to 5.8

I can complie a snippet with CC 5.8


Code:
#include<stdio.h>
#include<iostream.h>
int main()
{
int len=10;
char *coded = new char[len];
int *a=new int();
printf("Herllo");
cerr<<"Hello world:";
 cerr << "\nString Array Out of Bounds!! index: " << ":elem"
             << " String length (0-"
             <<" len" << ")\n";
int len1=strlen("idjfhdjfjtxt") + 1;
printf("%d\n",len1);
delete [] coded;
delete a;
}

Code:
CC sample.C
compiled well and good and i could see the out put when i run

Code:
CC --compat=4 sample.C
"Ccode.C", line 13: Error: The function "strlen" must have a prototype.
1 Error(s) detected.

How can i resolve this, as i am migrating my entire code during linking i am getting many symbol referencing errors as mentioned in previoues post


Thanks in advance,
Revathi R.

qfcvt_r

ECVT_R(3)						     Linux Programmer's Manual							 ECVT_R(3)

NAME

       ecvt_r, fcvt_r, qecvt_r, qfcvt_r - convert a floating-point number to a string

SYNOPSIS

       #include <stdlib.h>

       char *ecvt_r(double number, int ndigits, int *decpt, int *sign, char *buf, size_t len);

       char *fcvt_r(double number, int ndigits, int *decpt, int *sign, char *buf, size_t len);

       char *qecvt_r(long double number, int ndigits, int *decpt, int *sign, char *buf, size_t len);

       char *qfcvt_r(long double number, int ndigits, int *decpt, int *sign, char *buf, size_t len);

DESCRIPTION

       The  functions  ecvt_r,	fcvt_r,  qecvt_r  and  qfcvt_r are identical to ecvt, fcvt, qecvt and qfcvt, respectively, except that they do not
       return their result in a static buffer, but instead use the supplied buf of size len.  See ecvt(3) and qecvt(3).

NOTES

       These functions are obsolete. Instead, sprintf() is recommended.

CONFORMING TO

       These functions are GNU extensions.
