Arithmetic and Relational Operators in C

Program 1

#include<stdio.h>
#include<conio.h>
int main()
{
     system("cls");
     // Arithmetical operator + ,-, *,/%
         float a;
         a=15/2.0;
         printf("%.1f",a);
          
        // a=10;
        // b=5;
        // c=a+b;
        // printf("\nAddition is %d: ",c);
        // c=a-b;
        // printf("\nSubtraction is %d: ",c);
        // c=a*b;
        // printf("\nMultiplication is %d: ",c);
        // c=a/b;
        // printf("\nDivision is %d: ",c);
        // c=a%b;
        // printf("\nMod Result %d: ",c);
        // c=a%b;
     return 0;
}

Program 2

// Relational Operator
// > < >= <= == !=
#include<stdio.h>
#include<conio.h>
int main()
{
     system("cls");
     int a,b,c,x;
     printf("Enter two Number:");
     scanf("%d %d",&a,&b);
     c=(a==b);
     printf("a==b %d",c);
     c=(a!=b);
     printf("\na!=b %d",c);


    //  //c=a>b;
    //  //c=a>=b;
    //  //c=(a<=b);
    //   c=(a==b);
//    a=10;
//    b=10;
//    c=10;
//    x=(a==b==c);  // 1==10
  // printf("%d",x);
