Algorithm for To read the two complex numbers and perform the addition and multiplication of these two numbers

Description:

In this program the complex number means it contains the two parts . first one

is real part and second one is imaginary part(2+3i).by taking these two complex numbers we can perform the addition and multiplication operation.

Algorithm:

Step 1: Start

Step 2: declare structure for complex numbers

Step 3: read the complex number

Step 4: read choice

Step 5: if choice=1 then addition operation will perform and it contains following steps

i)    w.realpart = w1.realpart+w2.realpart;

ii)  w.imgpart = w1.imgpart+w2.imgpart;

 goto step 4

Step 6: if choice=2 then multiplication operation will perform and it contains following steps

i)    w.realpart=(w1.realpart*w2.realpart)-(w1.imgpart*w2.imgpart);

ii)                                  w.imgpart=(w1.realpart*w2.imgpart)+(w1.imgpart*w2.realpart);

goto step 4

Step 7: if choice=0 then exit operation will perform

Step 8:if w.imgpart>0 then print realpart+imgpart else

Print realpart.

Step 9: Stop
