Data Type 3

Let us understand arithmetic instruction:-

An instruction which is used to manipulate the data using operators is known as arithmetic instruction.

In C programming only one variable is allow before = symbol and after this there are no. of variable and constant can be used.

ex: a=b+c;  //correct

      a+b=c;  //incorrect

note:-

      a,b and c are data/operands and +,= is a operator

types of arithmetic instruction:-

1) integer mode:- an instruction in which all  operand are of type int.

             ex:- int a,b,c;

                    a=b+c;

2) real mode:- an instruction in which all are float(real) operand

            ex:- float a,b,c;

                 a=b*c;

3) mixed mode:- an instruction in which some operand are of int type and some are of float type.

            ex:- int a,b;

                    float c,d;

                    a=b*c-d;
