In C programming an arithmetic instruction contains a variable on left side of =(assignment operator) and variables names and constants on right side of =(assignment operator).
Syntax:- variable=(combination of variables and constants connected by arithmetic operators)
a=b+c-d*e/f;
Variables and constants together known as operands.
Variables and constants who appears on the right side of assignment operator connected by arithmetic operators like +,-,*,/ etc.
On the time of execution of an arithmetic statement first operands operated upon by the arithmetical operators and then the result assigned to the variable on the left hand side of =(assignment operator).
These arithmetic statements can be of 3 types as follows :-
1. Integer mode- All operands are of integer type.
for ex.- int a,b,c;
a=b+c+2;
2. Real mode- All operands are of real type.
for ex.- float a,b,c;
a=b+c+1.0;
3. Mixed mode- Some of the operands are integer type and some of the operands are of real type.
for ex.- int a,b;
float c,d;
d=a+b-c+2+3.5;
Points to note:-
1. Only one variable on left side of assignment operator.
for ex.- a=b+c; // correct
a+b=c; //Incorrect
