Write two functions, which read/write an array of records to/from a file. Write driver code to test the two functions. The driver code and the test output must show clearly that the file input and output work correctly

fwrite

// C program for writing  

// struct to file  

#include <stdio.h>  

#include <stdlib.h>  

#include <string.h>  

// a struct to read and write  

struct person  

{  

int id;  

char fname[20];  

char lname[20];  

};  

int main ()  

{  

FILE *outfile;  

// open file for writing  

outfile = fopen ("person.dat", "w");  

if (outfile == NULL)  

{  

 fprintf(stderr, "\nError opend file\n");  

 exit (1);  

}  

struct person input1 = {1, "rohan", "sharma"};  

struct person input2 = {2, "mahendra", "dhoni"};  

// write struct to file  

fwrite (&input1, sizeof(struct person), 1, outfile);  

fwrite (&input2, sizeof(struct person), 1, outfile);  

if(fwrite != 0)  

 printf("contents to file written successfully !\n");  

else

 printf("error writing file !\n");  

// close file  

fclose (outfile);  

return 0;  

}  

fread

// C program for reading  

// struct from a file  

#include <stdio.h>  

#include <stdlib.h>  

// struct person with 3 fields  

struct person  

{  

int id;  

char fname[20];  

char lname[20];  

};  

// Driver program  

int main ()  

{  

FILE *infile;  

struct person input;  

// Open person.dat for reading  

infile = fopen ("person.dat", "r");  

if (infile == NULL)  

{  

 fprintf(stderr, "\nError opening file\n");  

 exit (1);  

}  

// read file contents till end of file  

while(fread(&input, sizeof(struct person), 1, infile))  

 printf ("id = %d name = %s %s\n", input.id,  

 input.fname, input.lname);  

// close file  

fclose (infile);  

return 0;  

}  

answer; i do believe its (faster);

the benefits of raising bc’s minimum wage to $15 through a

series of pre-announced staged increases far outweigh the likely

costs. claims that such an increase will lead to massive job losses

in low-wage sectors of the economy are not credible.

• an increase to $15 would result in some job losses. however,

the likely impact is less than a 1 per cent reduction in the overall

provincial employment rate, and a 7.6 per cent reduction in the

employment rate for those currently making between $10.25

and $15 per hour.

• the large job loss impacts predicted by some opponents of

minimum wages misrepresent the existing economic research. in

reading and using that research, it is important to recognize that

estimates showing job loss effects of minimum wage increases

apply only to teenagers. estimated effects for young adult and

adult workers range from insignificant to non-existent.

• focusing on teenage workers plays up an inaccurate stereotype

about who earns very low wages in bc and leads to exaggerated

claims about job losses. only 26 per cent of those currently making

between $10.25 and $12 are teenagers, and only 5 per cent

of those making between $12 and $15 are teenagers.
