C program to perform basic arithmetic operations which are addition, subtraction, multiplication, and division of two numbers. Numbers are assumed to be integers and will be entered by a user. In C language when we divide two integers we get an integer as a result, for example, 5/2 evaluates to 2. As a general rule integer/integer = integer and float/integer = float or integer/float = float. So we convert denominator to float in our program, you may also write float in the numerator. This explicit conversion is known as typecasting.

Sets the decimal precision to be used to format floating-point values on output operations. Behaves as if member precision were called with n as argument on the stream on which it is inserted/extracted as a manipulator (it can be inserted/extracted on input streams or output streams). How to use setprecision in C. Ask Question. If i dont want to do a cout. Just want to set the precision of num1 to 3 decimal places. How do I do that? – ProgrammerOfGalaxies Jul 8 '18 at 22:12 show 1 more comment. When should we not do a post-doc after a Ph.D.?

For example, 5.567 should become 5.57 and 5.534 should become 5.53.

How

C programming code

#include <stdio.h>

int main()
{
int first, second, add, subtract, multiply;
float divide;
printf('Enter two integersn');
scanf('%d%d',&first,&second);
add = first + second;
subtract = first - second;
multiply = first * second;
divide = first /(float)second;//typecasting

printf('Sum = %dn', add);
printf('Difference = %dn', subtract);
printf('Multiplication = %dn', multiply);
printf('Division = %.2fn', divide);
return0;
}

Output of program:

Simple C++ Math[edit]

Math in C++ is very simple. Keep in mind that C++ mathematical operations follow a particular order much the same as high school math. For example, multiplication and division take precedence over addition and subtraction. The order in which these operations are evaluated can be changed using parentheses.

C++ math library[edit]

The C++ math library is actually C's math library. It is easy to use and is accessed by including cmath.
