7. Write a program that accepts user input for employee name and salary, and then display them using those variables.

#include <stdio.h>
int main()
{
char ename[50];

float salary;
// read the input and store them in variables
printf("\n Enter Employee name:\n ");
scanf("%[^\n]s",ename);
// Accept salary and store it
printf("\n Enter employee salary\n: ");
scanf("%f", &salary);
// Display the employee information
printf("\n Name of employee: %s", ename);
printf("\n Salary of Employee: %.2f",salary);
return 0;
}
Output:
Enter Employee name:
Raj
Enter employee salary
6000
Name of employee: Raj
Salary of Employee:6000.00

a program in c Programming language to find area of rectangle by accepting variable value width and length.

Explanation:
let understand how the program works step by step.
At the beginning of the program we have include the standard header file named stdio.h needed for the input and output functions such as printf() and scanf().Then we declared two variables.
First variable ename declared as array character that save the employee's name and another variable salary that uses a floating point or decimal number to save the amount of salary paid to the employee.
We have then used the printf function to ask the user to enter a name and then use scanf function to store the entered name.
A special format specifier %[^\n]s is used to confirm that an entire line is captured, including spaces.
Same way, we ask the user for salary using printf and then use scanf again to get his salary.
This time we use the %f format specifier to get a floating point value representing their salary.
After getting the user's name and salary, we display what he entered using printf.
We use %s to display name since it is s a string and %f to display salary since it is a decimal number.
Finally, the program exits and displays 0 which means everything successful.
