• == ‫مساوية‬
• <‫اصغر‬
• >‫اكبر‬
• ≤‫يساوي‬ ‫او‬ ‫اصغر‬
• ≥‫يساوي‬ ‫او‬ ‫اكبر‬
• ≠‫تساوي‬ ‫ال‬
logic
True/ 1
False/ 0

3. Example
• Int n1`=1, n2=3, n3=5;
• Int k1,k2;
• K1=(n1>n2);
• K1=0; false
• K2=(n1<= n3);
• K2=1; true
• The mathematical operators have a high
precedence over relational operation.

4. Example
• Int n1=1, n2=3, n3=5;
K1=n1<=n3*n2; n1<=15 True 1
K1=n3 == 5; 5 == 5 True 1
K1 = n3 == 5+3; n3 == 8 5 == 8 false 0
K1=(n3== 5)+3; (5==5)+3 1+3 4

5. Example
• Int n1=1, n2=3, n3=5;
K1= n1 <= n3 * n2;
K1= 1 <= 5 * 3;
K1= 1 <= 15;
K1 = True or 1

6. Example
• Int n1=1, n2=3, n3=5;
• K1 =n3 == 5;
• =5 == 5;
• = True
• K1= n3 == 5+3;
• = 5 == 8;
• = false
• K1= (n3 ==5) +3;
• =(5 == 5) +3
• =1 +3
• = 4
