Pointer to String in C

Pointer to String:

• A char* can points to a single character or a String.
• Char* holds the base address.
• We can process the strings using %s
• To process character by character, we use %c

#include<stdio.h>
int main()
{
	char* s = "Online-C";
	
	printf("%s \n", s);
	printf("%c \n", s);
	printf("%c \n", *s);
	printf("%c \n", *s+3);
	printf("%c \n", *(s+3));
	return 0;
}

#include<stdio.h>
void main()
{
	char* str = "learnown";
	printf("%c\n", *str++ + 3);
	printf("%s\n", ++str+2);
}

#include<stdio.h>
void main()
{
	char* str = "learnown";
	printf("%c\n" , *(str++ + 2)+3);
	printf("%c\n" , *++str+2);
	printf("%s\n" , --str-1);
}

Crack this code:

#include<stdio.h>
void main()
{
	char* str = "learnown";
	printf("%c\n",*((str-- +2)+1)-3);
	printf("%c\n", *(--str + 3)-32);
	printf("%c\n",*(++str+2)+4);
}

Output it:

#include<stdio.h>
void main()
{
	char sport[ ]= "cricket";
	int x=1 , y;
	y=x++ + ++x;
	printf(“%c”,sport[++y]);
}

A function can return the string using char* return type.

#include<stdio.h>
char* read(void);
int main()
{
	char* name;
	name = read();
	printf("Name returned by read function is : %s \n", name);
	return 0;
}
char* read(void)
{
	char* name;
	printf("Enter your name : ");
	gets(name);
	return name;	
}
