# Operators in C | Assignment Operator

Assignment Operators

The following table lists the assignment operators supported by the C language −

 Operator Description Example = Simple assignment operator. Assigns values from right side operands to left side operand C = A + B will assign the value of A + B to C

a=10
b=a;
c=b;
result:
a=10
b=10
c=10

```#include<stdio.h>
int main()
{
int a,b,c;
a=10;
b=20;
c=a+b;
printf("a = %d\n",a);
printf("b = %d\n",b);
printf("Sum = %d\n",c);
return(0);
}```

Output:

```a = 10
b = 20
Sum = 30```
 Operator Description Example += Add AND assignment operator. It adds the right operand to the left operand and assign the result to the left operand. C += A is equivalent to C = C + A

1.
int a,b,c;
a=10
a+=10; /* a=a+10; */
result:
a=20

2.
int a=10,b=20;
a+=10; /* a=a+10; */
b+=a; /* b=b+a; */
result:
a=20;
b=40;

```#include<stdio.h>
int main()
{
int a,b,c;
a=10;
printf("a = %d\n",a);
a+=10;  /* a=a+10 */
printf("a = %d\n",a);
return(0);
}```

Output:

```a = 10
a = 20```
```#include<stdio.h>
int main()
{
int a=10,b=20;
a+=10; /* a=a+10; */
b+=a; /* b=b+a; */
printf("a = %d\n",a);
printf("b = %d\n",b);
return(0);
}```

Output:

```a = 20
b = 40
```
 Operator Description Example -= Subtract AND assignment operator. It subtracts the right operand from the left operand and assigns the result to the left operand. C -= A is equivalent to C = C – A

1.
int a,b,c;
a=20
a-=10; /* a=a-10; */
result:
a=10

2.
int a=20,b=20;
a-=10; /* a=a-10; */
b-=a; /* b=b-a; */
result:
a=10;
b=10;

```#include<stdio.h>
int main()
{
int a=20,b=20;
a-=10; /* a=a-10; */
b-=a; /* b=b-a; */
printf("a = %d\n",a);
printf("b = %d\n",b);
return(0);
}```

Output:

```a = 10
b = 10
```
 Operator Description Example *= Multiply AND assignment operator. It multiplies the right operand with the left operand and assigns the result to the left operand. C *= A is equivalent to C = C * A
```#include<stdio.h>
int main()
{
int a=20,b=20;
a*=5; /* a=a*10; */
b*=10; /* b=b*10; */
printf("a = %d\n",a);
printf("b = %d\n",b);
return(0);
}```

Output:

```a = 100
b = 200
```
 Operator Description Example /= Divide AND assignment operator. It divides the left operand with the right operand and assigns the result to the left operand. C /= A is equivalent to C = C / A
```#include<stdio.h>
int main()
{
int a=20,b=20;
a/=5; /* a=a/10; */
b/=10; /* b=b/10; */
printf("a = %d\n",a);
printf("b = %d\n",b);
return(0);
}```

Output:

```a = 4
b = 2
```
 Operator Description Example %= Modulus AND assignment operator. It takes modulus using two operands and assigns the result to the left operand. C %= A is equivalent to C = C % A
```#include<stdio.h>
int main()
{
int a=20,b=20;
a%=3; /* a=a%3; */
b%=7; /* b=b%7; */
printf("a = %d\n",a);
printf("b = %d\n",b);
return(0);
}```

Output:

```a = 2
b = 6```
