5 a class, the establishment of a simple student information table, including student id, name, 3 course results, write a program that calculates the average scores and rankings, each student (note: define a structure type, with a structure pointer as a function parameter)

Input format:

Ld % s % % % f f % f

The output format:

% - 9-10 ld % s % 5.1 f % 5.1 f % % 8.1 f % 10.1 f - d \ n

Input the sample:

Zhao 201701 29.8 85.4 65.4
201702 qian 96.5 87.5 65.4
201703 sun 85.4 65.4 84.6
201704 li, 63.4 95.4 86.3
Zhou 201705 65.9 84.6 97.5

The output sample:

Number: Name: score: business: rank:
Zhao 29.8 85.4 65.4 60.2 5 201701
201702 qian 96.5 87.5 65.4 83.1 1
201703 sun 85.4 65.4 84.6 78.5 4
201704 li, 63.4 95.4 86.3 81.7 3
201705 zhou 65.9 84.6 97.5 82.7 2

No results? There is no output or the output is wrong? Results posted

CodePudding user response:

Char name;//visual here should be an array of strings

CodePudding user response:

A character array,,

CodePudding user response:

refer to the second floor m0_46108109 response:

char name;//visual here should be an array of strings

Here is how to change

CodePudding user response:

char name[20];

CodePudding user response:

If the rules how long name maximum input, the char name [len]//len for length
