int main(){
char *array[3];
scanf("%s",----); // The input is james.
return 0;
}
How can I store james in array[1] taking james as input so that it is equivalent to array[1] = "james"; ?. So the problem is that I have to take few strings as input and then I want to store it in an array such that it is stored like I have done array[1] = "James";
Please provide a code if possible.
You probably want something similar to this:
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
int main() {
char array[3][10]; // array of 3 strings of at most 9 chars
scanf("%s", array[0]);
scanf("%s", array[1]);
printf("%s\n%s\n", array[0], array[1]);
return 0;
}
Or by allocating memory dynamically:
int main() {
char *array[3];
array[0] = (char*)malloc(10); // allocate space for a string of maximum 9 chars
array[1] = (char*)malloc(10); // allocate space for a string of maximum 9 chars
// beware: array[2] has not been initialized here and thus cannot be used
scanf("%s", array[0]);
scanf("%s", array[1]);
printf("%s\n%s\n", array[0], array[1]);
return 0;
}
Disclaimer: there is absolutely no error checking done here, for brevity. If you enter a string of more than 9 characters, the behaviour of this program will be undefined.
Anticipating the next question: inspite of reserving space for 10 chars we can only store string of maximum length of 9 chars because we need one char for the NUL string terminator.
scanf("%9s",...What you should do is scanf("%s", array[1]); but since array[1] is a non-init pointer, you should first malloc() it with array[1] = malloc(length_of_your_string_plus_NUL_char);
#include<stdio.h>
#include<string.h>
#include<stdlib.h>
int main(){
char *array[3];
array[1] = malloc(100); // I used a large number. 6 would suffice for "James"
scanf("%99s", array[1]); // The input is james. Note the "99" (string width) addition that ensures you won't read too much and store out of bounds
return 0;
}
array[1]to point to, then you simply usearray[1]as the target argument forscanf. How to do this should be explained in every good beginners book.
