Character Manipulation Function

Special function was provided in standard library
C for manipulating character.
Refer to Jadual 12.1 (page 333) in
Pengaturcaraan C

Example
include ltstdio.hgt
include ltctype.hgt
int main()
char str18, str28
int x 0
printf("Masukkan satu perkataan ")
scanf("s", str1)
while (str1x ! '\0')
if (islower(str1x))
str2x toupper(str1x)
else
str2x str1x
x
str2x '\0'
printf("s dalam huruf besar s\n", str1,
str2)

Input one word
20

Example
include ltstdio.hgt
include ltctype.hgt
int main()
char str18, str28
int x 0
printf("Masukkan satu perkataan ")
scanf("s", str1)
while (str1x ! '\0')
if (islower(str1x))
str2x toupper(str1x)
else
str2x str1x
x
str2x '\0'
printf("s dalam huruf besar s\n", str1,
str2)

Copy every character
21

Example
include ltstdio.hgt
include ltctype.hgt
int main()
char str18, str28
int x 0
printf("Masukkan satu perkataan ")
scanf("s", str1)
while (str1x ! '\0')
if (islower(str1x))
str2x toupper(str1x)
else
str2x str1x
x
str2x '\0'
printf("s dalam huruf besar s\n", str1,
str2)

End of string character?
22

Example
include ltstdio.hgt
include ltctype.hgt
int main()
char str18, str28
int x 0
printf("Masukkan satu perkataan ")
scanf("s", str1)
while (str1x ! '\0')
if (islower(str1x))
str2x toupper(str1x)
else
str2x str1x
x
str2x '\0'
printf("s dalam huruf besar s\n", str1,
str2)

Is this small alphabet?
23

Example
include ltstdio.hgt
include ltctype.hgt
int main()
char str18, str28
int x 0
printf("Masukkan satu perkataan ")
scanf("s", str1)
while (str1x ! '\0')
if (islower(str1x))
str2x toupper(str1x)
else
str2x str1x
x
str2x '\0'
printf("s dalam huruf besar s\n", str1,
str2)

If yes, assign capital letter for that character
into array str2
24

Example
include ltstdio.hgt
include ltctype.hgt
int main()
char str18, str28
int x 0
printf("Masukkan satu perkataan ")
scanf("s", str1)
while (str1x ! '\0')
if (islower(str1x))
str2x toupper(str1x)
else
str2x str1x
x
str2x '\0'
printf("s dalam huruf besar s\n", str1,
str2)

If not, assign that character into array str2
25

Example
include ltstdio.hgt
include ltctype.hgt
int main()
char str18, str28
int x 0
printf("Masukkan satu perkataan ")
scanf("s", str1)
while (str1x ! '\0')
if (islower(str1x))
str2x toupper(str1x)
else
str2x str1x
x
str2x '\0'
printf("s dalam huruf besar s\n", str1,
str2)

Next index
26

Example
include ltstdio.hgt
include ltctype.hgt
int main()
char str18, str28
int x 0
printf("Masukkan satu perkataan ")
scanf("s", str1)
while (str1x ! '\0')
if (islower(str1x))
str2x toupper(str1x)
else
str2x str1x
x
str2x '\0'
printf("s dalam huruf besar s\n", str1,
str2)

Dont forget null character!!!
27
getchar() and putchar()

getchar() dan putchar() can be used for input and
output character

Example
include ltstdio.hgt
define MAKS 8
int main()
char strMAKS
int x 0
do
strx getchar()
x
while (x lt MAKS strx-1 ! '\n')
strx-1 '\0'
x 0
while (strx ! '\0')
putchar(strx)
x

Read character by character into an array
29

Example
include ltstdio.hgt
define MAKS 8
int main()
char strMAKS
int x 0
do
strx getchar()
x
while (x lt MAKS strx-1 ! '\n')
strx-1 '\0'
x 0
while (strx ! '\0')
putchar(strx)
x

Read next character
30

Example
include ltstdio.hgt
define MAKS 8
int main()
char strMAKS
int x 0
do
strx getchar()
x
while (x lt MAKS strx-1 ! '\n')
strx-1 '\0'
x 0
while (strx ! '\0')
putchar(strx)
x

Loop until there are no more items in array and
before users pushing enter
31

Example
include ltstdio.hgt
define MAKS 8
int main()
char strMAKS
int x 0
do
strx getchar()
x
while (x lt MAKS strx-1 ! '\n')
strx-1 '\0'
x 0
while (strx ! '\0')
putchar(strx)
x

Dont forget to insert null character into an
array
32

Example
include ltstdio.hgt
define MAKS 8
int main()
char strMAKS
int x 0
do
strx getchar()
x
while (x lt MAKS strx-1 ! '\n')
strx-1 '\0'
x 0
while (strx ! '\0')
putchar(strx)
x

Display an output for character by character
inside an array
33
gets() and puts()

These functions gets() dan puts() can be used for
input and output string

Example
include ltstdio.hgt

gets(str1)
printf("Masukkan rentetan 2 ")
gets(str2)
x 0
while (str2x ! '\0')
x
y 0
while (str1y ! '\0')
str2x str1y
x
y
str2x '\0'

Read two strings
35

Example
include ltstdio.hgt
int main()
char str15, str211
int x, y
printf("Masukkan rentetan 1 ")
gets(str1)
printf("Masukkan rentetan 2 ")
gets(str2)
x 0
while (str2x ! '\0')
x
y 0
while (str1y ! '\0')
str2x str1y
x
y
str2x '\0'

Find index for null character in str2
36

Example
include ltstdio.hgt
int main()
char str15, str211
int x, y
printf("Masukkan rentetan 1 ")
gets(str1)

str2x '\0'

Insert every character in Str1 at the end of
string in str2
37

Example
include ltstdio.hgt

strcmp()

strcmp() compares two string until unequal
characters are found or until the end of the
string is reached.
Prototype
int strcmp(char s1, char s2)
Return value strcmp()
If s1 lt s2, so strcmp(s1, s2) lt 0
If s1 gt s2, so strcmp(s1, s2) gt 0
If s1 equal to s2, so strcmp(s1, s2) 0
