Question

How to convert printf to puts in C?

printf("\tEmployee #:",employeeNumber); //employeeNumber is an int

printf("\tHourly Salary: $\%.1f \n",hourlySalary); //hourlySalary is a double

I need this to show up in one line using puts

It should look like this using puts:

Employee#: . . .

Hourly Salary: $ . . .

NOT LIKE:

Employee#:

. . .

Hourly Salary:

. . .

puts can be preferred to print the strings because it is less expensive than printf().

But puts moves the cursor to the next line. If you don't want new line you can use another version of puts.

That is:

syntax : fputs(str,stdout)

This is also work as puts but will not provide a new line.

Here is the code for given problem:

#include<stdio.h>
int main()
{
// % is intentionally put here to show side effects of using printf(str)
int emp_no;
double salary;
fputs("Employee# ",stdout);
scanf("%d",&emp_no);
fputs("Hourly Salary: $ ",stdout);
scanf("%f",&salary);
}
