Formatted Input. scan function in C
Formatted Input: Formatted input refers to an input data that has been arranged in a
particular format.
scanf(): Scanf() function can be
used input the data into the memory from
the standard input device. This function
can be used to enter any combination of numerical Values, single characters and
strings. The function returns number of
data items.
Syntax:-
scanf (“conversion strings”, &arg1,&arg2,--------&arg-n);
Where conversion
string reefers to a string containing certain required formatting
information and arg1, arg2----arg-n
are arguments that represent the individual input data items.
Example:
Where %s , %d, %f, %c with % are conversion
characters. The conversion characters
indicate the type of the to corresponding data. Commonly used conversion
characters for data input.
int a; float b; char n,sn[20];
scanf(“%d”,&a);
scanf(“%f”,&b;
scanf(“%c”,&n);
scanf(“%s”,sn);
scanf(“%d%f%c%s”,&a,&b,&n,sn);
Storage Class in C
The scope and lifetime of a variable or / and function within a C program is defined by storage class. There are four storage classes in C
auto - It is the default storage class for all variables and / or functions.
extern - It allows a global variable to be visible to all the program files / external files ( C programs).
Calculate Simple Interest with following detail. p=1000, n=5 and r=2.5
#include<stdio.h>
main()
{
int n=5;
float p=1000,r=2.5,si=0.0;
si=p*n*r/100;
printf("\nSimple Interest %.2f",si);
}
Output
Perform Simple Arithmetic Operation Program
Where a is 5 and b is 2.
+(Add) -(Subtraction) *(Multiplication
/ (Division) %(Remainder)
#include<stdio.h>
main()
{
int a=5,b=2,c,d,e,f,g;
c=d=e=f=g=0;
c=a+b;
d=a-b;
e=a*b;
f=a/b;
g=a%b;
printf("\nC=%d\nD=%d\nE=%d",c,d,e);
printf("\nF=%d\nG=%d",f,g);
}
Output
Note : if Both are Integer then result is
integer other wise Float.
Ex. (5/2.0 or 5.0/2 or 5.0/2.0 ----- 2.5)
Formatted Output
printf(): The printf() function is used to print the data from the computers memory onto a standard output device. This function can be used to output any combination of numerical values, single character and strings.
Syntax:
printf(“Control String Control Message Conversion String”, List of arg1 );
Where control string is a string that contains backslash characters, Control message that conations the user defined information and conversion string that contains formatted information, and list of arg. are arguments that represent the output data items.
A simple format specification has the following form:
%w.p type-specifier
Where w is an integer number that specifies the total number of columns for the output value and p is another integer number that specifies the number of digits to the right of the decimal point (of a real number) or the number of characters to be printed from a string. Both wad p are optional. Some examples of formatted printf statement are:
Example :
int a=6; float b=2.75; char d=’A’, city[10]=”KHAMMAM”;
Statement Output
printf(“Welcome To C Program”); Welcome To C Program
printf(“\nWelcome To C Program”); (skip line and Print next line)
Welcome To C Program
printf(“%d”,a); 5
printf(“%f”,b); 2.75
printf(“%c”,d); A
printf(“%s”,city); KHAMMAM
printf(“%d%f%c%s”,a,b,d,city); 52.75AKHAMMAM
printf(“%d\t%f\t%c\t%s”,a,b,d,city); 5 2.75 A KHAMMAM
printf(“A=%d\tB=%f\tD=%c”,a,b,d); A=5 B=2.75 D=A
Where %c %s %d %f are conversion characters.
Output of Integer Numbers: The format specification for printing an integer number is
%wd
Format Output
printf("%d", 9876) 9876
printf("%6d", 9876) _ _ 9876
printf("%2d", 9876) 9876
printf("%-6d", 9876) 9876_ _
printf("%06d", 9876) 009876
Output of Real Numbers
The output of a real number may be displayed in
decimal notation using the following format specification.
Ex.
y=98.7654
Format
Output
printf("% 7.4f",y) 98.7654
printf("%7.2f",y) _ _98.77
printf("%-7.2f",y) 98.77_ _
printf("%f",y) 98.7654
printf("%10.2e",y) _ _9.88e+01
printf("%11.4e",-y) -9.8765e+01
printf("%-l0.2e",y) 9.88e+01_ _
printf("%e",y) 9.876540e+01
Printing of a Single Character
A single character can be displayed in
a desired position using the format
%wc
The character will be displayed right-justified the field of w columns. We can make the display left-Justified by placing a minus sign
before the integer w. The default value for w is 1.

Backslash Character (Only Output)
C supports some special backslash character constants that are used in output function.
"\a" Alert or bell
"\b" Back space
"\f" Form Feed
"\n" New line
"\r" Return
"\t" Tab
"\v" Vertical tab
"\\" Print \ (back slash)
"\?" Print ?
"\'" Print ' (Single Quote)
"\"" Print " (Double Quote)
"\0" Null
"%%" Print %
