for loop in C returning only first value of array

I'm a beginner. Well I was just trying out my hand at data structures and could not understand why I was getting the error. I think it would be better to post the code and the output I'm getting. (I use the C-Free 4.0 Compiler), by the way. So here's the code

// Write a C program to enter and display elements of an array

    #include <stdio.h>
    int main(int argc, char *argv[])
{
    int a[44],n,i=0;
    // No. of elements:
    printf("\n How many elements in all?");
    scanf("%d",&n);

    // Entering all elements:
    printf("\n\n Plz do enter the elements:");
    for(;i<n;i++)
    scanf("%d",&a[i]);

    // Displaying all elements:
    printf("\n Array elements are:");

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

       printf("\n a[%d]=%d",i,a[i]);
       i++;
       break;

     }

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

    {
      sum=sum+a[i];

    }

    printf("\nSum=%d",sum);


    return 0;
}
/*
  And here's the output when I say that I'm entering 3 elements into the array:

   How many elements in all?3


 Plz do enter the elements:12
0
-22

 Array elements are:
 a[0]=12
Sum=-10Press any key to continue . . . */

Well as you all can see, I am able to enter values for(i=0;i

for(i=0;i<n;)
{
   printf("\n a[%d]=%d",i,a[i]);
   i++;
   break;
}

Here the break statement you are using is getting you out of the loop. remove the break statement and it will print all the elments of the array....

for() loop can be used in two ways,

for (Start value; end condition; increase value)
        statement;

or

Start value = initialization;
for (; end condition;){
        statement;
        increase value;
}

In your code, the Start value is initialized to i = 0 so you can try any of the ways but preferably first is accepted more for ease and clarity.

for(i=0;i<n;)
{
   printf("\n a[%d]=%d",i,a[i]);
   i++;
   break;
}

You have put a break; so it only prints 1 element.

Remove that break; and it will print all.

Also you can put that i++ just next to the condition i<n as shown below.

for(i=0;i<n;i++)
{
    printf("\n a[%d]=%d",i,a[i]);
}
