c:conio.h:cgets

cgets

char *cgets(char *str);

description of cgets

Reads a string from the console.

cgets reads a string of characters from the console and stores the string (and the string length) in the location pointed to by str.

cgets reads as long as a sign to mark the combination carriage return / line feed (CR / LF) occurs or the maximum number of characters has been read. When reading cgets the CR / LF combination is replaced by the combination of characters \ 0 (null terminator) before the string is stored.

Assign str[0] before calling cgets to the maximum length of the string to be read.
After completion of the read operation st is assigned[1] the actual number of characters read.
The reading begins with the character at position str[2] and ends with the null terminator.
Consequently, at least str str[0] in length plus 2 bytes.

return value: a pointer to str[2]

#include <stdio.h>
#include <conio.h>
int main(void)
{
   char buffer[83];
   char    *p;
   buffer[0] = 81;
   printf("Input some chars:");
   p = cgets(buffer);
   printf("\ncgets read %d characters: \"%s\"\n", buffer[1], p);
   return 0;
}

output of cgets c example

  Input some chars: 123
  cgets read 3 characters
