Learn Basic Operators of C Programming

1: Syntax for code:
#include<stdio.h>
main()
{
printf("");
}
  Example:
#include<stdio.h>
main()
{
printf("Hai");
}
2(a).Addition of two numbers[in run time]:
#include<stdio.h>
main()
{
int a,b;
printf("enter two values:");
scanf("%d%d",&a,&b);
printf("sum is :%d",a+b);
}

 (b). Addition of two numbers[temperary]:
#include<stdio.h>
main()
{
int a=2,b=3;
printf("sum is :%d",a+b);
}

(c). Addition of two numbers[decimals]:
#include<stdio.h>
main()
{
float a=10.234;
double b=17.567;
float c=a+b;
printf("%.2f\n%lf\n%f",a,b,c);
}

3.Arthmetic operators[+,-,*,/,%]:

#include<stdio.h>
main()
{
int a,b;
printf("enter two values:");
scanf("%d%d",&a,&b);
printf("sum is :%d",a+b);
printf("\nsubtraction is :%d",a-b);
printf("\nmulti is :%d",a*b);
printf("\ndivision is :%d",a/b);
printf("\nmodule is :%d",a%b);
}

(OR)

#include<stdio.h>
main()
{
float a,b;
printf("enter two values:");
scanf("%f%f",&a,&b);
printf("sum is :%f",a+b);
printf("\nsubtraction is :%f",a-b);
printf("\nmulti is :%f",a*b);
printf("\ndivision is :%f",a/b);

}

4. Assignment operators[=,=+,=-,=*,=/,=%]:

#include<stdio.h>
main()
{
int a,b;
printf("enter two values:");
scanf("%d%d",&a,&b);
printf("sum is :%d",a+=b);
printf("\n%d",a);
}

5. Relational opertaors[==,<,>,<=,>=,!=]:

#include<stdio.h>
main()
{
char ch;
printf("Enter a value");
scanf("%c",&ch);
(ch>=A&&ch<=Z)||(ch>=a&&ch<=z)?printf("alpa"):printf("not");
}

6. Increment[++] and Decrement[--]:

#include<stdio.h>
main()
{
int a=4,b;
b=++a;
b=a--;
printf("a=%d\nb=%d\n",a,b);
}
