Program with If(illustration)
#include<stdio.h>
#include<conio.h>
void main()
{
int a,b;
printf("enter the value in variables");
scanf("%d %d",&a,&b);
if(a >b)
{
printf("a is greater");
}
}
Output:
Program with If-else(find greater among two no.)
#include<stdio.h>
#include<conio.h>
void main()
{
int a,b;
printf("enter the value in variables");
scanf("%d %d",&a,&b);
if(a >b)
{
printf("a is greater");
}
else
{
printf("a is smaller");
}
}
Output:
Program with else-if(find the grades like 90>=A, 70>=B, 50>=C, 40>=Pass, 40<=Fail)
#include<stdio.h>
#include<conio.h>
void main()
{
int mark;
printf("enter your marks");

{
printf("C Grade");
}
else if(mark >=40)
{
printf("Pass");
}
else if(mark <40)
{
printf("Fail");
}
}
Output:
#include<stdio.h>
#include<conio.h>
void main()
{
float a,b;
int c;
printf("enter two values");
scanf("%f %f",&a,&b);
printf("/n enter 1-add /n 2-sub /n 3-mul /n 4-div /n 5-average");
scanf("%d",&c);
if(c==1)

else if(c==4)
{
printf("div = %f ", a/b);
}
else if(c==5)
{
printf("avg = %f ", (a/b)*100);
}
}
Output:
Program with Else-if(printing good morning,afternoon, night etc)
#include<stdio.h>
#include<conio.h>
void main()
{

printf("enter time ");
scanf("%d",&t);

{
printf("Good Afternoon");
}
else if(t<=20)
{
printf("Good Evening");
}
else if(t<=24)
{
printf("Good night");
}
}
Output:
Program with switch statement( print dayname with date)
#include<stdio.h>
#include<conio.h>
void main()
{
int d;
printf("enter the date ");
scanf("%d",&d);
switch (d)
