Scanning and Printing a sentence in C

AchyutMS

I wrote the following C program which gets a sentence as input and print it back as output:

#inlcude<stdio.h>
int main()
{
  char string[30]; 
  scanf("%s ",string);
  printf("\n %s ",string);
  return 0;
}

Sample Input:
India is Best

Output got:
India

Why cant i get the whole sentence?

Use gets() function to get string. Here C finds the input with first space only.

This is because the scanf will scan the characters untill the first space occurs. If you want to scan the white spaces, you can use fgets.

Try using the following statement instead of scanf()

fgets(string,30,stdin);

AchyutMS use gets() instead of scanf()

Sudhakar gets() is removed from #include<studio.h> read gets() section in forum

AchyutMS

Sudhakar But gets() function has been removed from C99. So it gives error when we use gets().

Sorry bro I didn't read that one. Now ,I read it.

AchyutMS
Here is your solution bro.use

scanf("%[^\n]%*c", string);

Here we used the %[^/n] to avoid that whitespace problem.

Srivignesh So does the values get stored in stdin? And will they get erased once the program is done compiling?

Syntax of fgets()
fgets(variable_name, number_of characters_to_scan, file_stream)
here we used the standard input device as a file stream. stdin stands for standard input device.the value that you entered during runtime will be stored in the variable only.
