C Programming: Accept a string from keyboard

C String: Exercise-1 with Solution

Write a program in C to input a string and print it.

C Programming: Accept a string from keyboard

Sample Solution:

C Code:

#include <stdio.h>  
#include <stdlib.h>  
  
void main()
{
    char str[50];
	
    printf("\n\nAccept a string from keyboard :\n");
    printf("-----------------------------------\n"); 	
    printf("Input the string : ");
    fgets(str, sizeof str, stdin);
    printf("The string you entered is : %s\n", str);
}

Sample Output:

Accept a string from keyboard :                                                                               
-----------------------------------                                                                           
Input the string : Welcome, w3resource                                                                        
The string you entered is : Welcome, w3resource

C Programming: Tips of the Day

Is there a way to specify how many characters of a string to print out using printf()?

The basic way is:

printf ("Here are the first 8 chars: %.8s\n", "A string that is more than 8 chars"); 

The other, often more useful, way is:

printf ("Here are the first %d chars: %.*s\n", 8, 8, "A string that is more than 8 chars"); 

Here, you specify the length as an int argument to printf(), which treats the '*' in the format as a request to get the length from an argument.

You can also use the notation:

printf ("Here are the first 8 chars: %*.*s\n",
        8, 8, "A string that is more than 8 chars"); 

This is also analogous to the "%8.8s" notation, but again allows you to specify the minimum and maximum lengths at runtime - more realistically in a scenario like:

printf("Data: %*.*s Other info: %d\n", minlen, maxlen, string, info); 

The POSIX specification for printf() defines these mechanisms.
