Array Comparison in C Solved

Question

Hello, I would like to know if there is a command in C that allows you to compare two arrays and determine all the elements that these two arrays have in common. Thank you.

If it's a character array, you can use strcmp (<string.h>). Otherwise

int cmp_tab(int *tab1,int *tab2,int size){ // or whatever you want instead of "int" for(i=0;i<size;i++) { if (tab1[i]!=tab2[i]) return 0; } return 1; }

or something like that...

Note that if you can use C++, you can directly use the vector class and the == operator...

Hello,

What type of arrays would you like to compare?
Char, int, ...? One-dimensional or two-dimensional?
There is a function to compare two strings "strcmp" but for the rest, I think we'll have to code it.

Hello, You will do it faster by coding a function than by looking for a ready-made one!!! In my opinion, that's the best...  -- Thai Proverb: Penguins in the fields,  very harsh winter.

Hello  Mamienando, I don't understand why your function returns 2 values  return 0;  return 1;

Hello,  the function returns 0 if element i of tab1 is not equal to element i of tab2 otherwise the function returns 1  so there is only one value returned -- lami20j

mamiemando · Answer

Exactly, so if the two arrays are of size "size": - if they are equal, the function returns 1 - if they have at least one different element, the function returns 0.

Hello, how do we compare two arrays T1 and T2?  such that:  char* T1[10][10]; char* T2[10][10];  we want to know if the two arrays have the same values.   Thank you in advance;

mamiemando · Answer

To complement what mype says, try to do something like this int compare_array(const char* A1[10][10], const char* A2[10][10]){ unsigned i, j; for(i=0; i

Hi,

Currently, I am working on a project regarding football management.

When adding a team, I want to check if that team already exists or not, for which I need to test if the two teams do not have the same coach, the same players, and the same technical staff.

Here is the structure of the team that I used:

-----------------------------------------------------------------------------------------------

typedef struct{
char* name[35]; //team name
char* player[23][35]; //array of players
char* coach[35];
char* staff[5][35]; //array of technical staff
} Team;

------------------------------------------------------------------------------------------------

So I want to write a function that compares two arrays of strings, i.e., to compare the players of team 1 with the players of team 2.

Thank you in advance.

Here is the complete code (or at least the minimal code that shows that the test does not work). Another question, are you constrained to programming in C or are you allowed to use C++?  Good luck

mamiemando · Answer

When I say complete code, I mean something that can be compiled and executed, and that highlights the problem. I'm still waiting to know if we can use C++ features (which would greatly simplify the code).

Good luck

```c
#include

int fonctionErronee(int a) {
    return a + 1; // La fonction est censée faire quelque chose de différent
}

int main() {
    int resultat = fonctionErronee(5);
    printf("Le resultat est : %d
", resultat);
    return 0;
}
```
