disk-file-read-write

explain

  • This program realizes the read-write operation of disk file, for example, read the student's score information from scores.txt by line.
  • The student information in the file is as follows
姓名	数学分析	高等代数	解析几何
张红	78	94	90
李丽君	65	73	82
成平	94	68	78
王伟	84	86	69
文锦春	74	92	60
林黛玉	66	83	70
付凌云	88	79	82
岳不群	90	82	93
令狐冲	81	77	97
温玉琪	95	84	68
胡建军	85	73	75
刘汉	90	87	89
秋昌平	83	71	74
秦敖天	96	92	95
方世杰	83	90	88
  • The next action is to store each line of student information read in the structure studentInfo
  • Then the data in the structure are used to calculate the average score of the course and the average score of each person.
  • The average scores of the courses and the average scores of the students are written into the scoresAnalysis.txt file in a certain format.
  • The situation in the scoresAnalysis.txt file is as follows
姓名		数学分析	高等代数 	解析几何	平均成绩
张红		78		94		90		87.3
李丽君		65		73		82		73.3
成平		94		68		78		80.0
王伟		84		86		69		79.7
文锦春		74		92		60		75.3
林黛玉		66		83		70		73.0
付凌云		88		79		82		83.0
岳不群		90		82		93		88.3
令狐冲		81		77		97		85.0
温玉琪		95		84		68		82.3
胡建军		85		73		75		77.7
刘汉		90		87		89		88.7
秋昌平		83		71		74		76.0
秦敖天		96		92		95		94.3
方世杰		83		90		88		87.0
各科平均成绩	83.5		82.2		80.7
  • The last step is to use the file pointer to read and display the contents of the scoresAnalysis.txt by row to the console window
