Question

Find the distinct elements in a given array in c

Answer 1

Answer:

You have not set the initial value of m to be equal to zero - it is undefined....

you also need to reset distinct to 1 for each element of the array you test. (in fact you don't need the variable distinct see below)

You also need to change the j loop - it should be

for(j=0; (j<m)&&(distinct==1); j++)

because j needs to loop through the array w

with these fixes it works.... (see below)

#include <stdio.h>

#include <stdlib.h>

int main()

{

int v[100], w[100], n, m=0, i, j, distinct=1;

printf("n= ");

scanf("%d", &n);

for(i=0; i<n; i++)

{

printf("v[%d]= ", i);

scanf("%d", &v[i]);

}

distinct=1;

for(i=0; i<n; i++)

{

for(j=0; (j<m)&&(distinct==1); j++)

if(v[i]==w[j])

distinct=0;

if(distinct==1)

{

w[m]=v[i];

m++;

}

}

printf("the distinct elements are: ");

for(i=0; i<m; i++)
