The program what will read a number followed by a series of bit operations from file and perform the given operations sequentially on the number is given below.
<h3>What is an operation in computer science?</h3>
An operation, in mathematics and computer programming, is an action that is carried out to accomplish a given task.
There are five basic types of computer operations:
- Inputting,
- processing,
- outputting,
- storing, and
- controlling.
<h3>What is the requested program above?</h3>
#include <stdio.h>
#include <fcntl.h>
int main(int argc, char *argv[])
{
int number, n, v, temp;
char line[25], fun[10];
FILE *f = fopen(argv[1], "r");
fgets(line, 24, f);
sscanf(line, "%d", &number); //reading the number
while( fgets(line, 24, f) )
{
sscanf(line, "%s %d %d", fun, &n, &v); //reading the commands
switch(fun[0]) //checking which command to run
{
case 'g': temp = 1;
temp = temp<<n; //shifting for getting that bit
printf("%d\n",(number&temp)&&1);
break;
case 's': temp = 1;
temp = temp<<n; //shifting for setting that bit
if(!v)
{
temp = ~temp;
number = number & temp;
}
else
{
number = number | temp;
}
printf("%d\n",number);
break;
case 'c': temp = 1;
temp = temp<<n; //shifting for complimenting that bit
number = number ^ temp; //xor to complement that bit
printf("%d\n",number);
break;
default:printf("not defined");
}
}
return 0;
}
Execution and Output:
terminal-> $ gcc -o first first.c
terminal-> $ ./first file1.txt
