Then gets() function reads the characters from the stdin and places them into the character array pointed to by str. Characters are read until a newline or an EOF is received. The newline character is not made part of string; instead, it is translated into a null to terminate string.
#include<stdio.h> char *gets(char *str);
The gets() function returns str on success, otherwise returns a null pointer on failure.
Following c program uses gets() function to read a filename:
C Programming Source Code:#include<stdio.h>
#include<conio.h>
#include<stdlib.h>
void main()
{
clrscr();
FILE *fp;
char fname[20];
printf("Enter filename : ");
gets(fname);
fp=fopen(fname, "r");
if(fp==NULL)
{
printf("Error in opening the file..!!\n");
printf("Press any key to exit..\n");
getch();
exit(1);
}
fclose(fp);
getch();
}
