Write a program in the Pascal programming language. A natural number N is given.

Write a program in the Pascal programming language. A natural number N is given. Find the sum 1 + 2 + 3 + 4 + 5 +… + N.

The program will be written in the PascalABC.net programming language;

We will find the sum of numbers up to n using the counter of the for loop and write the value into a separate variable, since the loop step is 1.

begin // start of the program;

var sum: = 0; // initialization of the variable, into which the value of the sum of elements will be written, assigning the initial value to the variable;

for var i: = 1 to n do

sum + = i; // formation of the amount;

writeln (sum); // display the value of the sum;

end. // end of the program;
