Inverse of the list

<source lang="cpp">#include<stdio.h>

1. include<conio.h>

void read(int *,int); void dis(int *,int); void inverse(int *,int); main(){

  int a[5],i;
  read(a,5);
  dis(a,5);
  inverse(a,5);
  dis(a,5);
  getch();

} void read(int c[],int i) {

  int j;
  printf("Enter the list \n");
  for(j=0;j<i;j++)
     scanf("%d",&c[j]);
  fflush(stdin);

} void dis(int d[],int i) {

  int j;
  printf("The list is \n");
  for(j=0;j<i;j++)
     printf("%d ",d[j]);
  printf("\n");

} void inverse(int inver_a[],int j) {

  int i,temp;
  j--;
  for(i=0;i<(j/2);i++)
  {
     temp=inver_a[i];
     inver_a[i]=inver_a[j];
     inver_a[j]=temp;
     j--;
  }

Enter the list
1
2
3
4
5
The list is
1 2 3 4 5
The list is
5 2 3 4 1

Use another list to hold the reversed list

<source lang="cpp">#include<stdio.h>

1. include<conio.h>

void read(int *,int); void dis(int *,int); void inverse(int *,int *,int); main(){

  int a[5],b[5];
  read(a,5);
  dis(a,5);
  inverse(a,b,5);
  dis(b,5);
  getch();

} void read(int c[],int i) {

  int j;
  printf("Enter the list \n");
  for(j=0;j<i;j++)
     scanf("%d",&c[j]);
  fflush(stdin);

} void dis(int d[],int i) {

  int j;
  printf("The list is \n");
  for(j=0;j<i;j++)
     printf("%d ",d[j]);
  printf("\n");

} void inverse(int a[],int inverse_b[],int j) {

  int i,k;
  k=j-1;
  for(i=0;i<j;i++)
  {
     inverse_b[i]=a[k];
     k--;
  }

}</source>

Enter the list

The list is
1 2 3 4 5
The list is
5 4 3 2 1
