Thread: string and pointer

but I don't know how to initialize a array of strings.

Code:

char history_table[HISTORY_SIZE][MAX_CMD_LEN] = {0};

will set the whole array to be contain empty strings

Here :

Code:

#include <stdio.h>
#include <math.h>
#include <string.h>
#include <ctype.h>

#define HISTORY_SIZE 10
#define MAX_STRING_LEN 100
#define  MAX_CMD_LEN 10

void printHistory( char history[][MAX_CMD_LEN], int size);
int processCommand( char *current, char *cmd, char *result); 
void updateHistory( char history[][MAX_CMD_LEN], const char *cmd, int size)={0};

int main(void)
{
	int i;
	char cmd[MAX_CMD_LEN]="";
	char current[MAX_STRING_LEN]="";
	char result[MAX_STRING_LEN]="";
	char history_table[HISTORY_SIZE][MAX_CMD_LEN]={};
	
	int history_size = 0;
	int flag;

	printf("Enter command [help] for a list of commands\n");

	do {
		
		printf("cmd> ");
                        fflush(stdout)
		gets(cmd); //get a command from user.

                        if(strcmp( cmd, "hist") == 0) {
			printHistory( history_table, history_size);
		}
		else {
			flag= processCommand(current, cmd, result);
		}

         if( cmd !="")
{
	   updateHistory(history_table, cmd, history_size);
	   history_size++;
}

	}while (flag!=1);
	return 0;
}

void updateHistory( char history[][10], const char *cmd, int size)
{
	
	ctrcpy(history[size],cmd);
	
	
}
void printHistory( char history[][MAX_CMD_LEN], int size)
{
	int i,j;
	printf("Size of history: &#37;d\n", size);
	for( i=0; i<size; i++)
	{
		puts(history[i]);
		printf("\t");
	}
}

won't compile

Code:

'ctrcpy': identifier not found
