Design Ideas

(1)
1. Carefully observe the meaning of the question and sort out the general steps on the paper;
2. Design the program and write it;

Run it after the end to see if the answers and requirements are consistent.

Experimental code

#include<stdio.h>
#include<string.h>
int main()
{
    struct nam
    {char name[10];
     float a;
     float b;
     float c;

    int N=3,i;
    scanf("%d",&N);
    for(i=0;i<N;i++)
    scanf("%s%f%f%f",&stu[i].name,&stu[i].a,&stu[i].b,&stu[i].c);
    for(i=0;i<N;i++)
    printf("%s %.2f\n",stu[i].name,stu[i].a+stu[i].b-stu[i].c); 
    }

(4). Problems encountered in the debugging process of this question and solutions
Error message 1: When inputting 'stu[10000]', input '10000' to '100000', so that the program cannot run normally.
Error reason: unknown.
Modification method: Change '100000' to '10000'.

(4). Problems encountered in the debugging process of this question and solutions
Error message 1: When inputting char [10], inputting '10' to '5' causes the program running result to be incorrect.
Error reason: unknown
Modification method: Change 'char[5]' to 'char[10]'
