Strings in C

Character type array is called string. All strings end with the NULL character. Use the %s placeholder in the printf() function to display string values.

Declaration:
char name[50];
Example
#include
void main (void )
{
char *st1 = "abcd";
char st2[] = "efgh";
printf( "%s\n", s1);
printf( "%s\n", s2);

}

void main(void){

char myname[] = { 'S', 't', 'e', 'v', 'e' };

printf("%s \n",myname);
}

String input and output:
The gets function relieves the string from standard input device while put S outputs the string to the standard output device.

The function gets accepts the name of the string as a parameter, and fills the string with characters that are input from the keyboard till newline character is encountered.
The puts function displays the contents stored in its parameter on the standard screen.
The syntax of the gets function is
gets (str_var);

The syntax of the puts character is
puts (str_var);
Example:

# include <>
Void main ( )
{
char myname [40];
printf (“Type your Name :”);
gets (myname);
printf (“Your name is :”);
puts(myname);
}

strcat(string1, string2)	Concatenate string2 onto the end of string1
length = strlen(string)	Get the length of a string
strcmp(string1, string2)	Return 0 if string1 equals string2, otherwise nonzero
strchr(string1, chr);	will find the first matching character in a string.
