i want to modify that c program that the user enters only floats.

[jkamugisha]

             // c program to add 10 elements entered by the user
            #include <stdio.h>  
            int main ()
            {   
              int i;    
              float elements[10];       //declaring the array
              float sum = 0;

              for (i = 0; i < 10; ++i)
                {
                  printf ("Enter element %d: ", i + 1); //getting the elements from the user
                  scanf ("%f", &elements[i]);   //storing the elements
                  sum += elements[i];   //adding integers entered by the user to the sum variable

                }

              printf ("sum of above entered elements is : %.4f", sum);  //printing the sum to four decimal places
              return 0;
            }

kindly help because i have tried and tried but i could not get the exact output i wanted

Line 12 seems to input floats. But your reply now writes you can not get the exact output you wanted but didn't share what happened versus what you wanted.

First you appear to have mark this solved.

Second, you mention "output" a second time yet you neglect to share what the output was and share what you wanted the output to be.
