I am writing a very simple code where the input will be like:

First line will have number of strings user will enter. Eg:2

Print the string

char str[20];   
int TC=0;
scanf("%d",&TC); //get number of strings
while(TC!=0){ //read all the strings and print
    fgets(str,19,stdin);
    printf("%s\n",str);
    TC--;
}

The code takes N-1 input strings from user rather than N.

I bet this is a duplicate of all the other `scanf` questions. TL;DR: Rule 1: Don't use `scanf`. Rule 2 (experts only): Don't use `scanf` for user input. – melpomene Jun 27 '16 at 21:31

@melpomene And how else is he supposed to read an int in ANSI C? – PSkocik Jun 27 '16 at 21:34

@PSkocik See the second link above (basically `fgets` + `atoi` or whatever). – melpomene Jun 27 '16 at 21:34
