this is what i've gotten so far I am not sure if i have defined all the correct variables, then i am not sure what to set to 0, also i don't believe i defined the limit variable correctly

help please in C++

Write a program that asks the user for a positive integer value between 2 and 100 inclusively. The program should use a while loop to compute the sum of all integers from 1 up to the number entered. For example, if the user enters 50 , the loop will find the sum of 1,2,3,4, 50 and after the loop terminates, output the message, "Sum of numbers 1+2++50 is 1275 ". If the user enters an integer less than 2 or an integer greater than 100, the program should give the error message, "Invalid entry. Integer should be between 2 and 100. " and then terminate. Hint: You will need a counter and an accumulator. If needed, reference slide 2 of Lect5a_Part2_while_cont.pptx. Create a limit variable, take the input from user and populate it, and then use it in the while loop in place of 10. When the input as is shown in Figures 1&3, your program should produce the output as shown in Figures 2&4. Figure 1: (sample input) 50 Figure 2: (sample output, your output should actually include the ++ and not the actual numbers) Sum of numbers 1+2++50 is 1275 Figure 3: (sample input) 2 Figure 4: (sample output) 345678910111213141516171819202122232425262728//Lab28#includeusingnamespacestd;intmain(){//definevariablesintsum,num;//defineaccumulatorvariableandinitializeitto0intsum=0//definealimitvariabletobeinputbutusercin>>num;//readinthelimit//validatethelimitisbetween2and100inclusivelyif0return0
