Create a report of this program
and Explain each section of code ( I need this for semester project report file )

Answer 1

Analysis: This program needs to be corrected first because this program code contains multiple errors. And without rectifying the errors this program cannot be executed successfully.

Test Result:
main.c: In function ‘main’:
main.c:100:1: warning: implicit declaration of function ‘getche’ [-Wimplicit-function-declaration]
getche();

^~~~~~
main.c: In function ‘accept’:
main.c:114:1: warning: ‘gets’ is deprecated [-Wdeprecated-declarations]
gets(array[i].name);

^~~~
In file included from main.c:9:0:
/usr/include/stdio.h:638:14: note: declared here
extern char *gets (char *__s) __wur __attribute_deprecated__;

^~~~
main.c: In function ‘load’:
main.c:125:9: warning: format ‘%s’ expects argument of type ‘char *’, but argument 2 has type ‘char (*)[20]’ [-Wformat=]
scanf("%s",&fname);

^~~~
/tmp/cc1vv8XU.o: In function `accept':
main.c:(.text+0x40f): warning: the `gets' function is dangerous and should not be used.
/tmp/cc1vv8XU.o: In function `main':
main.c:(.text+0xc): undefined reference to `clrscr'
main.c:(.text+0x347): undefined reference to `getche'
collect2: error: ld returned 1 exit status

Conclusion: This program code can be used only after rectifying the proposed corrections.
