How to use matrix in C?-CodePudding

I want to print the 3 city names by using matrix in C?

#include <stdio.h>
#include <stdlib.h>

int main() {
    
    char city[15];
    int i;
    
    for(i=0;i<3;i  )
    {
        printf("Enter the city");
        scanf("%s",city[i]);
    }
    for(i=0;i<3;i  )
     {
        printf("The city that was entered");
        printf("%s",city[i]);
     }
    return 0;
}

CodePudding user response：

char is a single character, and char city[15] is an array of 15 characters.

To store 15 strings (one for each city name) it would need to be like char city[15][101]. This would allow 100 characters for each city name, plus the terminating 0 character. (Strings in C get a 0 char at the end).

Then scanf("%s",city[i]) would work.

However if the user enters more than 100 characters for the city name, it would cause a buffer overflow. A way to prevent this is to use scanf("0s",city[i]);.
