Int main shouldn't be put in it, instead use start and the cout and cin shouldn't be in flow chart, please make the flowchart refer to this pict example

start Enter no of element Calculate: kun Increase i area Enter type of element Enter number of width Enter number of height Element=triangle Enter number of width Enter number of height Element=rectangle Enter number of radius Element-circle Enter number of radius Element quarter Enter noof element
