Can you please help me?

Question

The code c++ does not give correct results for the ascending arrangement of an array (one dimension), what is fail here?

int arr[4] , val=0;
cout<<"Enter Value Array:\n"<<"--------------------\n";
for(int i=0 ; i<4 ; i++)
cin>>arr[i];
for(int i=0 ; i<4 ; i++){
for(int j=1 ; j<4; j++)
if (arr[j]<arr[i]){
val=arr[j];
arr[j]=arr[i];
arr[i]=val;
}
}
for(int i=0 ; i<4 ; i++)
cout<<arr[i]<<"\t";

Answer 1

for(int i=0 ; i<4 ; i++){
for(int j=0 ; j<4; j++) // initialise 'j' with 0.
if (arr[j]<arr[i]){
val=arr[j];
arr[j]=arr[i];
arr[i]=val;
}
}

Answer 2

thank's

Answer 3

You can also initialise the 'i' to 1, together with the 'j' to 0;
