Difference between switch and ladder if in c language

1. Difference between Switch and ladder if:-
If else :--else if is the control statement which controls the statement(s) to be executed on the basis of
some condition. When we use else-if, the condition is checked and if the condition is true corresponding
statement(s) is executed. If the condition is false, it continues checking the next else-if statement until the
condition becomes true or the control comes to the end of all else-ifs.
switch :--In this case, a statement is written inside switch, and then, the probabale cases are written.
Now, when control comes to the switch statement, it compares the value with the cases, if it matches any
cases, corresponding statements inside the case is executed n the control checks for next statement, and
do the same, until it reaches the end of the switch. To, make the prog execute only one case, v use break
inside every case.
Diff :----
In case of else-if, the control checks every else-if statement until it find true value of the statement or it
comes to the end of the else-ifs. In case of switch, according to the value of switch, the control jumps to
the corresponding case.
When, we want multiple types of statements to be executed when condition becomes true, we should use
switch without break in the case. Whereas in case of else-if, we will have to use the common statements
in desired else-ifs, which causes duplication of some of the statements.
Example:-
If …. else ladder Switch
Switch(a)
{
case 1 : cout<<”red”;
break;
case 2: cout<<”orange”;
break;
case 3: cout<<”yellow”;
break;
}
If(a==0)
Cout<<”red”;
Else if (a==1)
Cout<<”orange”;
Else if (a==2)
Cout<<”yellow”

2. Check a Character is vowel or not
If..else switch
#include<stdio.h>
main()
{
char n;
printf("enter charcter");
scnaf("%c",&n);
if(n=='a'||n=='e'||n=='i'||n=='o'||n=='u')
{
printf("vowels");
}
else
{
printf("not vowels");
}
}
#include<stdio.h>
main()
{
char n;
printf("enter charcter");
scanf("%c",&n);
switch(n)
{
case 'a':
case 'e':
case 'i':
case 'o':
case 'u':
printf("vowel");
break;
default:
printf("not vowel");
}
}

3. Week Day Program
#include<iostream>
using namespace std;
main()
{
int week;
cout<<"enter day";
cin>>week;
if(week==0)
{
cout<<"sunday";
}
else if(week==1)
{
cout<<"monday";
}
else if(week==2)
{
cout<<"tusday";
}
else if(week==3)
{
cout<<"wensday";
}
else if(week==4)
{
cout<<"thusday";
}else if(week==5)
{
cout<<"friday";
}
else if(week==6)
{
cout<<"satuday";
}
else
{
cout<<"wrong input";
}
}
#include<iostream>
using namespace std;
main()
{
int week;
cout<<"enter day";
cin>>week;
switch(week)
{
case 1:
cout<<"monday";
break;
case 2:
cout<<"tuseday";
break;
case 3:
cout<<"wensday";
break;
case 4:
cout<<"thusday";
break;
case 5:
cout<<"friday";
break;
case 6:
cout<<"satuday";
break;
case 7:
cout<<"sunday";
break;
default:
cout<<"wrong input";
}
}
