Define and write syntax of gets()

gets() reads a whole line (a string, including spaces) from the keyboard into a character array and replaces the new line with '\0'. It is declared in <stdio.h>.

Syntax: gets(string_variable);

#include <stdio.h>
int main(void)
{
    char name[30];
    printf("Enter your full name: ");
    gets(name);
    printf("Hello, %s\n", name);
    return 0;
}

Output (for the input Ram Bahadur Thapa):

Enter your full name: Hello, Ram Bahadur Thapa

gets() does not check the array size, so a long input overflows the array. It was removed in C11, and gcc warns that it is deprecated. The safe alternative is fgets(name, sizeof(name), stdin);.
