I need to read serial numbers from many .csv files. Within these files, the serial number located in the first column, second row, and is of the form Eng SN = XX0000X000000. What I need to read is just the serial number, and not the Eng SN portion, so everything after the = sign. To clarify, in the serial numbers, the X is just a place holder for some other letter and the 0 is a place holder for some other number. I know I will need to use fopen, fclose etc. I am just stuck on what format spec to use since there is a mixture of letters and numbers.
