I'm trying to create a code to remove the same elements in arrays. The problem is EXC_BAD_ACCESS (Code = 1, address = 0x30000008) issue. When I'm trying to run my code here it is. `

#include <math.h>
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
int main()
{
    srand (time(NULL));
    int i, j, b, c;
    double A[11];
    double B[10];
    char choice;
    for (i = 0; i < 11; i  )
    { 
        A[i] = rand () 0;
    } 
        
    for (j = 0; j < 10; j  )
    {
        B[j] = rand () % 100;
    }

    
    printf("Array A[N]: \n");
        for (i = 0; i < 10; i  )
    {

        printf("%.2lf  ", A[i]);
    }
    printf("\n Array B[M]: \n");
        for (j = 0; j < 10; j  )
    {
        printf("%.2lf  ", B[j]);
    }
    for (i = 0; i < 11; i  )
    {
        for (j = 0; j < 10; i  )
        {
          **  if (A[i]==B[j])
Exception has occurred.
EXC_BAD_ACCESS (code=1, address=0x16fe00000)**
            {
                for (c = j; c < 10; c  )
                {
                    B[c] = B[c 1];
                }
                j--;
            }
        }
    }
    printf("\n New array B[M]: \n");
    for ( j = 0; j < 9; j  )
    {
        printf ("%.2lf", B[c]);
    }
    
    return 0;
}

` Hope for helping. Thank you

I was trying to define N 11 and M 10, so it would work, but, unfortunately, not.

CodePudding user response：

for (c = j; c < 10; c  ){
     B[c] = B[c 1];
}
j--;

In this part if c = 9 (last iteration), you have B[9] = B[10]; The size of B is 10, so the maximum value of the index has to be 9.

My solution is the following:

#include <math.h>
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
int main()
{
    srand (time(NULL));
    int i, j, b, c;
    double A[11];
    double B[10];
    char choice;
    for (i = 0; i < 11; i  )
    { 
        A[i] = rand () 0;
    } 
        
    for (j = 0; j < 10; j  )
    {
        B[j] = rand () % 100;
    }

    
    printf("Array A[N]: \n");
        for (i = 0; i < 10; i  )
    {

        printf("%.2lf  ", A[i]);
    }
    printf("\n Array B[M]: \n");
        for (j = 0; j < 10; j  )
    {
        printf("%.2lf  ", B[j]);
    }
    int max_j = 10;
    for (i = 0; i < 11; i  )
    {
        for (j = 0; j < max_j; j  )
        {
            if (A[i]==B[j])
            {
                for (c = j; c < max_j-1; c  ) {
                    B[c] = B[c 1];
                }
                B[max_j-1] = 0;
                max_j--;
            }
        }
    }
    printf("\n New array B[M]: \n");
    for ( j = 0; j < 9; j  )
    {
        printf ("%.2lf ", B[j]);
    }
    
    return 0;
}
