Pointer to array of character: A pointer to such an array which contents is character constants is known as pointer to array of character constant.

What will be output if you will execute following code?


#include<stdio.h>

char display(char (*)[]);

int main(){

char c;

char character[]={65,66,67,68};

char (*ptr)[]=&character;

c=display(ptr);

printf("%c",c);


return 0;

}

char display(char (*s)[]){

**s+=2;

return **s;

}

Output: C

Explanation: Here function display is passing pointer to array of characters and returning char data type.

**s+=2

=>**s=**s+2

=>**ptr=**ptr+2 //s=ptr

=>**&character= **&character+2 //ptr=&character

=>*character=*character+2 //from rule *&p =p

=>character[0]=character[0]+2 //from rule *(p+i)=p[i]

=>character [0] =67

**s=character [0] =67

Note: ASCII value of ‘C’ is 67
