I have a logic error in my C++ code, my task is to code five function where each will be responsible of checking its own parameters.

five functions:

-bool isValidQC(string results) This function returns true if its parameter is a well-formed test result string described above or false otherwise.

-int passQC(string results) If the parameter is a well-formed test result string, this function should return the total number of pass test results from all the batches reported in the string. If the parameter is not valid, return -1 .

-int defectQC(string results) If the parameter is a well-formed test result string, this function should return the total number of defect test results from all the batches reported in the string. If the parameter is not valid, return -1.

-int totalQC(string results) If the parameter is a well-formed test result string, this function should return the total number of tests being reported from all the batches in the string. If the parameter is not a valid, return -1. -int batches(string results) If the parameter is a well-formed QC test result string, this function should return the total number of batches reported in the string. If the parameter is not a valid, return -1.

Suppose that an automated manufacturing tracker records production QC test results in batches in a results string. For example, Q2p1d1 would indicate that a single batch of two QC tests was performed with the results of one pass and one defect. Note that the character Q is used to start a batch of QC test results. The character p is to identify the number of tests that passed the QC test, and the character d indicates the number of defects. More than one batch of QC test results can be reported in a single results string. For example, Q2d1p1Q5p3d2 would indicate two batches of QC test results, one with two test results and one with five test results, with a combined total of four passes and three defects. Precisely, to be a valid QC test results string, - a batch of results must begin with the character Q (case sensitive) - a batch of results must report both pass and defect test results with p and d in either order - no leading zeros are allowed in any numeric value being reported - the total number of QC tests in a batch must equal the number of pass and defect test results. - the total number of QC tests in a batch must be greater than zero (0). - a single result string may include multiple batches of results

when I test 1 batch for example Q5d2p3

all the out puts are correct, out put example:

Enter a possible teststring: Q5d2p3

isValidQC returns true

pass test result(s) returns 3

defectQC(s) returns 2

totalQC(s) returns 5

batches(s) returns 1

But when I test with 2 or more batches:Q5d2p3Q5d2p3

the output is incorrect:

Enter a possible teststring: Q5d2p3Q5d2p3

isValidQC returns true

pass test result(s) returns 3

defectQC(s) returns 6

totalQC(s) returns 15

batches(s) returns 2

CAN SOMEONE FIX THIS ASAP?
