$(30\%)$ Write a C# program to display the sum of $1+2+3+$dots$+10$ like below:

Sum of $1+2+3+$dots$+10$ is $1$ in iteration $1$

Sum of $1+2+3+$dots$+10$ is $3$ in iteration $2$

Sum of $1+2+3+$dots$+10$ is $6$ in iteration $3$

Sum of $1+2+3+$dots$+10$ is $45$ in iteration $9$&

Sum of $1+2+3+$dots$+10$ is $55$ in iteration $10$

$($Since when we add $1+2+3+4+$dots etc. we get $1,1+2=3,1+2+3=6$ etc.$)$

Note. This is a simple application of for loop but you have a Console. WriteLine in each iteration with the value

sum changed in every iteration$).$

Capture the output in the Word file and turn in the source code.
