2 a Write in C language a subroutine void add64int64 result

2. a. Write in C language a subroutine void add_64(int64 *result, int64 *oper1, int64 *oper2) The subroutine adds two 64-bit numbers. b. The numbers are presented as a struct, which has to be declared in a header file add64.h. In the struct there are two variables unsigned int lo32 and unsigned int hi32. c. Write a main () subroutine that initializes the struct variables and calls add_64 subroutine.

Solution

#include main() { FILE *fp; char ch; fp = fopen(\"one.txt\", \"w\"); printf(\"Enter data\"); while( (ch = getchar()) != EOF) { putc(ch,fp); } fclose(fp); fp = fopen(\"one.txt\", \"r\"); while( (ch = getc(fp)! = EOF) printf(\"%c\",ch); fclose(fp); }
