The execution with totalnumber = 0 and the input of the character string HH! causes twoexecutions of the loop body. At both executions the false-branch of the selection is passedthrough. The exclamation mark terminates the loop executiontest path: n start , n 1 , n 2 , n 3 , n 5 , n 2 , n 3 , n 5 , n 2 , n finald. The execution with totalnumber = 0 and the input of the character string HA! causes twoexecutions of the loop body. At the first execution the false-branch of the selection ispassed through. At the second execution the true-branch of the selection is passedthrough. The exclamation mark terminates the loop executiontest path: n start , n 1 , n 2 , n 3 , n 5 , n 2 , n 3 , n 4 , n 5 , n 2 , n final• The seven test cases are sufficient for the complete test of the loop according tothe boundary interior criterion41
