ADDITION & SUBTRACTION OF TWO COMPLEX NUMBERS USING C PROGRAM

C code:
1. Adding two complex numbers in c
2. C program for addition of two complex numbers
3. C program to add two complex numbers

#include<stdio.h>
int main(){
int a,b,c,d,x,y;
printf("\nEnter the first complex number:");
scanf("%d%d",&a,&b);
printf("\nEnter the second complex number:");
scanf("%d%d",&c,&d);
if(b<0)
printf("%d-i\n",a-b);
else
printf("d+i\n",a+b);
if(d<0)
printf("d-i\n",c-d);
else
printf("%d+i\n",c+d);
x=a+c;
y=b+d;
if(y>0)
printf("%d-i%d",x,-y);
else
printf("%d+i%d",x,+y);
printf("\n\nSUBTRACTION ");
x=a-c;
y=b-d;
if(y<0)
printf("%d-i%d",x,-y);
else
printf("%d+i%d",x,+y);
return 0;
}

1. Does multiplication of complex number programing diifers from addition ? since it leads to squaring of variable whats the logic of program.

2. if(b<0) x="a+c;" y="b+d;">0)

doesnt work?

"nonportable pointer conversion"

&

"statment missing ;"

sorry im just a begginer at C n would like to understand.

Your code has some syntactical error. So first you should read c tutorial of this blog

Addition of two matrix is very simple compare to multiplication.
For addition of two matrix of take two for loop add each element of one matrix with corresponding element of other matrix one by one and store in another two dimensional array.
a[i][j]=b[i][j]+c[i][j]
