Similar GATE Doubts

The procedure given below is required to find and replace certain characters inside an inputcharacter string supplied in array A. The characters to be replaced are supplied in array oldc,while their respective replacement characters are supplied in array newc. Array A has a fixedlength of five characters, while arrays oldc and newc contain three characters each. However, theprocedure is flawedvoid find _ and _ replace (char A, char oldc, char * newc ) {for (int i= 0; i <5; i++)for (int j =0; j <3; j++)if (A [i] ==oldc[ j]) A [i]= newc [j] ;}The procedure is tested with the following four test cases(1) oldc = "abc", newc = "dab" (2) oldc = "cde", newc = "bcd"(3) oldc = "bca", newc = "cda" (4) oldc = "abc", newc = "bac"Q.The tester now tests the program on all input strings of length five consisting of characters‘a’, ‘b’, ‘c’, ‘d’ and ‘e’ with duplicates allowed. If the tester carries out this testing with thefour test cases given above, how many test cases will be able to capture the flaw?
