Count of Prime Numbers between 2 and 100

code

givenNumber = 100
startFrom = 2
total = 0

while startFrom <= givenNumber:

    iterateFrom = 1
    count = 0

    while iterateFrom <= startFrom:

        if startFrom % iterateFrom == 0:
            count+=1

        iterateFrom = iterateFrom + 1

    if count == 2:
        total = total + 1


    startFrom = startFrom + 1

print (total)

output

Sum of Prime Numbers

code

givenNumber = 100
startFrom = 2
total = 0

while startFrom <= givenNumber:

    iterateFrom = 1
    count = 0

    while iterateFrom <= startFrom:

            count+=1

        iterateFrom = iterateFrom + 1

    if count == 2:
        total = total + startFrom


    startFrom = startFrom + 1

print (total)

output
