Question

q7.1 Fix the errors in the code (in C)

//This program should read a string from the user and print it using a character pointer

//The program is setup to use pointer offset notation to get each character of the string

#include <stdio.h>

#include <string.h>

int main(void){

char s[1];

scanf(" %c", s);

char *cPtr = s[1];

int i=0;

while(1){

printf("%c", cPtr+i);

i++;

}

printf("\n");

}

Answer 1

CODE IN C:-(With documentation and required correction)

#include <stdio.h>

#include <string.h>

int main(void){

char str[100]; //STRING CAN BE OF LENGTH MORE THAN 1 so we need to take length more than 1

scanf(" %s", str);

char *cPtr = str; //to store the address of first character in string just write character array name

while(*cPtr) //Here we cannot take 1 inside while() because if we take 1 then it will always be true and run for infinite times
{

printf("%c", *cPtr++); //to access the value of address we need to use * before it and also instead of using *cPtr+i each time //we can use *cPtr++

}

printf("\n");

}
