C – Reading Strings

Program to read and display string:

int main() {             char name[20];             printf(“Enter your name : “);             scanf(“%s”, name);                         printf(“Hello %s, Welcome to Strings \n”, name);             return 0; }

How %s read input into String variable:

• “%s” takes the base address of memory block.
• It reads character by character and stores from the base address.
• Once input is over, it will add null character at the end of the string.

Program to read multi-word string in C:

• gets() function can read a string with multiple spaces.
• It stops reading characters into array only when we hit “enter” key.

int main() {             char name[20];             printf(“Enter multi word name : “);             gets(name);             printf(“Hello %s \n”, name); }
