- Arrays can
be divided into two categories.
1.

Basic of Looping Structures
-
In certain situation in programming, statement(s)
are required to be repeated for fixed number of times or till certain condition
is satisfied.
-
C language provides looping structures so that we
need not to write those statement(s) again and again in our program. If the
Write a program to find sum of first N odd numbers.
#include<stdio.h>
#include<conio.h>
void main()
{
int i, num, odd=0,
even=0;
clrscr();
printf(“Enter the number:”);
scanf(“%d”,&num);
for(i=1;i<=num,i++)

Features / Importance of C.
- C
is a robust:
C language provides 32 keywords. It has a
rich set of functions and operators. We can use them to write any complex programs.
- C
is fast and efficient:
C language consists of variety of data types
and powerful operators which makes it faster.

Nested if-else statement:
- The
if-else statement provides two way decisions only.
- Sometimes,
decisions must be made between more than two possibilities.
- At that
time, we can use nested-if else statement.
- C
language provides nested-if else. Nested if else means loop within loop.
- In, nested
if else statement, if the condition is true than statement(s)-1 (or statement(s)-2)
is executed.
- If the
condition is false then statement(s)-3 (or statement(s)-4) is executed.
- Syntax:
if(condition)
{
if(condition)
{
Statement(s)-1;
}
else
{
Statement(s)-2;
}
else
{
if(condition)
{
Statement(s)-3;
}
else
{
Statement(s)-4;
}
}
- Example: A C program to find out the largest number among three
numbers.
#include<stdio.h>
#include<conio.h>
void
main()
{
int a,b,c;
clrscr();
printf("Enter the values of a: ");
scanf("%d",&a);
printf("Enter the values of b: ");
scanf("%d",&b);
printf("Enter the values of c: ");
scanf("%d",&c);
if(a>b)
{
if(a>c)
{
printf(" a is largest number.");
}
else
{
printf(" c is largest number.");
}
}
else
{
if(b>c)
{
printf(" b is largest number.");
}
else
{
printf(" c is largest number.");
}
}
getch();
}
OUTPUT:
Enter the values of a:15
Enter the values of b:25
Enter the values of c:45
if else statement
- In, if else
statement, if the condition is true than statement(s)-1 is executed.
- If the
condition is false then statement(s)-2 is executed.
- Syntax:
if(condition)
{
Statement(s)-1;
}
else
{
Statement(s)-2;
}
- Flow chart:
 |
| if else statement |
- Example: A C program to check the student is pass or fail.
#include<conio.h>
#include<stdio.h>
void main()
{
float
per;
clrscr();
printf(“enter
the percentage:”);
scanf(“%f”,&per);
if(per>35)
{
printf(“Student
is pass.”);
}
else
{
Printf(“Student
is fail.”);
}
getch();
}
OUTPUT:
enter the percentage: 28
Student is fail.
