Add elements into an array in C

[Marria]

Hello everyone! I have to make a program - french-english dictionary controled by a menu with three functions: search, add and remove words. I have a problem with the add function but i don't now what is the problem. I'm posting the entire code here just in case:

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

char words[][2][40]={
      {"adorer","adore"},
      {"gras","greasy"},
      {"outil","tool"},
      {"radis","radish"},
      {"tracer","trace"},
      {"",""}
};


void Search(void);
int menu(void);
void Save(void);
void Load(void);
void Display(void);   
void Add(void);

int main(void){
    int choice;

    //Load();

    do{
        choice = menu();

        switch(choice){
            case 1: Load();
                break;

            case 2: Save();
                break;

            case 3: Search();
                break;

            case 4: Display();
                break;

            case 5: Add();
                break;
      }
    }while(choice!=6);

    return 0;
}


int menu(void){
    char str[80];
    int i;

    printf("1. Load\n");
    printf("2. Save\n");
    printf("3. Search\n");   
    printf("4. Display\n");
    printf("5. Add new words\n");


    do{
        printf("Enter your choice:(1-5) \n");
        gets(str);
        i=atoi(str);
        printf("\n");
    }while(i<1 || i>5);

    return i;
}


void Search(void){

    char word_fr[40];
    int i, size;

    size=sizeof(words)/sizeof(words[0]);

    printf("Enter french word: ");
    gets(word_fr);

    for(i=0; i < size; i++)
        if(!strcmp( word_fr, words[i][0]))
            printf("%s %s\n", words[i][0], words[i][1]);


}

void Save(void){
     FILE *fp;
     int i,size;

     size=sizeof(words)/sizeof(words[0]);

     if(( fp=fopen( "diction.txt", "w" )) == NULL) {
          printf("Save says: Cannot open file.\n");
          exit(1);
     }
    
     for(i=0; i < size; i++) {
         fprintf( fp, "%s %s ", words[i][0], words[i][1]);
     }
     fclose(fp);
}

void Load(void)
{

    FILE *fp;
    int i,size;

    size=sizeof(words)/sizeof(words[0]);

    if(( fp=fopen( "diction.txt", "w+" )) == NULL ) {
        printf("Load says: Cannot open file.\n");
        exit(1);
    }

    for(i=0; i < size; i++) {
        fscanf( fp, "%s %s", words[i][0], words[i][1]);
    }
    fclose(fp);
    printf("The file was loaded successfully.\n");
}

void Display(void)
{
    int i,size;

    size=sizeof(words)/sizeof(words[0]);

    for(i=0; i < size; i++) {
        printf("%s %s\n", words[i][0], words[i][1]);
    }
}

void Add(void)
{


    char str[40];
    int size;

    size=sizeof(words)/sizeof(words[0]);

    printf("Enter french word:\n ");
    gets(str);


    strcpy(words[size][0], str);

    printf("Enter english word:\n ");
    gets(str);

    strcpy(words[size][1], str);

    Save();
}

I'm using Turbo C/C++ because i'm obliged to present my project on this compiler. I'll be thankful if someone helps me.

I have a problem with the add function but i don't now what is the problem.

We don't either since you are the only one that has seen wha happens (or does not happen).
You need to describe the problem.

When i choose "5" from the menu, i enter the french and the english word and press "ENTER" it gives me this:

Enter french word: musique
Enter english word: music
musique2. Save
3. Search
4. Display
musicusicEnter your choice:(1-5)

And it's not adding the words in the array.

Maybe engage in the discussion on your other thread over here -> Writing, Reading And Searching In A File In C - C And C++ | Dream.In.Code

Because it seems like you're just wandering from one forum to another hoping someone will fix all your issues without you having to understand anything, or do anything.

Salem all fryday i'm searching in the net and the forums for people with the same problems, i changed tons of things in my program and i'm not stopping doing it. But i'm sorry that i dont understand where the problem is. Maybe i really should do something more...
Sorry for the inconvinience.

I don't think size=sizeof(words)/sizeof(words[0]); is doing what you want.

When you add an entry, simply count it.
This count tells you exactly how many entries you have at all times. New entry, increase the count.

The flaw is in your thread title. You can't add elements to an array in C. You can only copy elements into an array.
