A symbol that directs the compiler to execute particular mathematical or logical operations is known as an operator. The C programming language has a large number of built-in operators, including the following:

Arithmetic Operators It contains addition, subtraction, multiplication, division, modulus operations, increment, and decrement, as well as other fundamental arithmetic operations.

Mathematical computations are carried out using arithmetic operators. The assignment operators are used to give a property or variable a value. Numeric, date, system, time, and text can all be used as assignment operators. To accomplish comparisons, comparison operators are employed.

```
//Sum of Two Numbers in C Program
#include <stdio.h>
int main()
{
int a, b, sum;
printf("Enter two integers");
scanf("%d %d", &a, &b);
sum = a + b;
printf("%d + %d = %d", a, b, sum);
return 0;
}
```

Output:

Enter two integers 45

45

45 + 45 = 90
