I'm kind of new to C, but not to programming. I'm trying to create a program that takes an input and replies with a random string that's already saved in an array (for example).
I'm not trying to create a random string, I want them to be "fixed", like in Java:
String [] sa;
sa[0] = "Hello, World";
sa[1] = "Hi dude!";
#include <stdio.h>
#include <stdlib.h>
int main() {
const char *messages[] = {
"Hello!",
"How are you?",
"Good stuff!"
};
const size_t messages_count = sizeof(messages) / sizeof(messages[0]);
char input[64];
while (1) {
scanf("%63s", input);
printf("%s\n", messages[rand() % messages_count]);
}
return 0;
}
It's not clear as to what you exactly want, but here is a brief description of how strings work in C.
There are no String like data type in C as you have in Java. You have to use array of characters. For an array of strings, you have to use two dimensional array of characters.
char myStrings[MAX_NUMBER_OF_STRING][MAX_LENGTH_OF_STRING];
Here what your are looking for:
#include <stdio.h>
#include <stdlib.h>
int main(int argc, char** argv)
{
char buffer[42];
const char *mytext[] = {"A1", "A2", "A3"};
scanf("%41s", buffer);
srand(time(NULL));
printf("Random text: %s\n", mytext[rand() % (sizeof(mytext) / sizeof(mytext[0]))]);
return 0;
}
#include<stdio.h>
#include<stdlib.h>
int main(){
char str[7][100]={"hello1","hello2","hello3","hello4","hello5","hello6","hello7"};
printf("%s",str[rand()%7]);
return 0;
}
printf("%s\n", sa[rand() % 2]);
