Reading Strings from Terminal

In C, you can read strings from the terminal using various methods. Here are a few common ways to do it:

• Using scanf:
Program.c
#include <stdio.h> int main() { char str[100]; printf("Enter a string: "); scanf("%s", str); printf("You entered: %s\n", str); return 0; }

Output:
Enter a string: Hello World
You entered: Hello

• Using gets (deprecated, use with caution):
Program.c
#include <stdio.h> int main() { char str[100]; printf("Enter a string: "); gets(str); printf("You entered: %s\n", str); return 0; }

Output:
Enter a string: Hello World
You entered: Hello World

• Using fgets:
Program.c
#include <stdio.h> int main() { char str[100]; printf("Enter a string: "); fgets(str, sizeof(str), stdin); printf("You entered: %s\n", str); return 0; }

Output:
Enter a string: Hello World
You entered: Hello World

• Using character-wise input:
Program.c
#include <stdio.h> int main() { char str[100]; int i = 0; char c; printf("Enter a string: "); while ((c = getchar()) != '\n' && i < sizeof(str) - 1) { str[i++] = c; } str[i] = '\0'; printf("You entered: %s\n", str); return 0; }

Output:
Enter a string: Hello World
You entered: Hello World

• Using %[^\n]s inside scanf:
Program.c
#include <stdio.h> int main() { char input[100]; printf("Enter a line of text: "); scanf("%[^\n]s", input); printf("You entered: %s\n", input); return 0; }

Output:
Enter a line of text: Hello World!
You entered: Hello World!
