Using strchr() and moving the cursor up one row

My first question is this:
Is there a way that I can use strchr() to find the next character occurance, not the first or last, or for it to find the character after a certain point? I tried

Code:

---

char input[]="abcdabcdabcd";
int x=5;
strchr(input[x], 'd')

---

but it returns an error message: error C2664: 'strchr' : cannot convert parameter 1 from 'char' to 'const char *'.
My second question is:
Is it possible to move the cursor(in the command prompt screen) up one row? I have this really old Turbo C++ book that says I must use ANSI.SYS, but thats for DOS(from like before 1990).
Thanks

try &input[x].

But which compiler do you have.
And which operating system for that matter.

This is the help page from Turbo C/C++ ver. 1:

Code:

strchr  Finds c in str.

 Syntax:
 char *strchr(const char *s, int c);

 Prototype in:
 string.h

 Remarks:
strchr scans a string in the forward direction, looking for a specific
character. strchr finds the first occurrence of the character c in the
string s.

The null-terminator is considered to be part of the string, so that, for
example,

    strchr(strs,0)

returns a pointer to the terminating null character of the string strs.

 Return Value:
Returns a pointer to the first occurrence of the character c in s. If c does
not occur in s, strchr returns null.

 Portability:
strchr is available on UNIX systems and is defined in ANSI C.

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

int main(void)
 {
    char string[15];
    char *ptr, c = 'r';

    strcpy(string, "This is a string");
    ptr = strchr(string, c);
    if (ptr)
      printf("The character %c is at position: %d\n", c, ptr-string);
    else
      printf("The character was not found\n");
    return 0;
 }

I'm assuming you either have an early version of Turbo C/C++, or are thinking of getting it.

For moving the cursor, you can use the non-standard conio.h include file.

I am using Visual C++ 6.0, in Windows XP. Thanks for the help!
But can anyone tell me how to move the cursor upwards?

You mean like this?

You may need a getxy first, then gotoxy with a --y index -

Code:

---

// Sets the position of the text-cursor, starts at 0, 0 on the
// top left
void GotoXY        ( int  x, int  y )
{
    COORD Cursor_Position;

    Cursor_Position.X = x;
    Cursor_Position.Y = y;

    SetConsoleCursorPosition( GetStdHandle ( STD_OUTPUT_HANDLE ), Cursor_Position );
}

// Gets the current position of the text-cursor
void GetXY        ( int &x, int &y )
{
        CONSOLE_SCREEN_BUFFER_INFO XYInfo;

        GetConsoleScreenBufferInfo( GetStdHandle( STD_OUTPUT_HANDLE ), &XYInfo );

        x = XYInfo.dwCursorPosition.X;
        y = XYInfo.dwCursorPosition.Y;
}

C doesn't have references. Your code is C++.
