• C program to take a paragraph as input from user using scanf function.
• How to take a multi line input form user using getchar function.

Required knowledge: scanf function

"%[^;]s" specifies that scanf will take all characters as input except ';' character. As soon as user enters ';' character scanf function stops reading input and returns.

C program to take multiline string input from user using scanf function.

#include<stdio.h>

int main() {
   char inputString[128];
 
   printf("Enter a multi line string( press ';' to end input)\n");
   scanf("%[^;]s", inputString);
 
   printf("Input String = %s", inputString);
 
   return 0;
}

Output

Enter a multi line string( press ';' to end input)
The quick brown for Jumps
over the lazy
dog;
Input String = The quick brown for Jumps
over the lazy
dog

C program to take a paragraph as input from user using getchar function.

#include<stdio.h>

int main() {
   char inputString[128], c;
   int index = 0;
 
   printf("Enter a multi line string( press ';' to end input)\n");
   while((c = getchar()) != ';'){
       inputString[index++] = c;
   }
   inputString[index] = '\0';

   printf("Input String = %s", inputString);
 
   return 0;
}

Output

Enter a multi line string( press ';' to end input)
