CodePudding user response:

Two inner lining for (j... ) more cycle and fscanf_s () less & amp; X [I]. Num.

CodePudding user response:

Inner loop j useless?

CodePudding user response:

reference 1st floor QZJHJXJ response:

two lining for (j... ) more cycle and fscanf_s () less & amp; X [I]. Num.

Changed or not

CodePudding user response:

reference 1st floor QZJHJXJ response:

two lining for (j... ) more cycle and fscanf_s () less & amp; X [I]. Num.

Only the first listed Numbers

CodePudding user response:

File is 20 rows five columns

CodePudding user response:

Fills his belly, and then fill in the file??

CodePudding user response:

Reference:

//description: because the compiler doesn't support fopen_s () and fscanf_s () function, so instead of the corresponding fopen () and fscanf ().
