Assignment No. 5 Strings.
Objectives: To study the string. The string is collection
of characters which end with null (‘\0’) character.
1. Write
a program to accept the string and count the length of string without using
standard library function.

Program Name:Write
a program to accept the string and count the length of string without using standard library function.
#include<stdio.h>
#include<conio.h>
void
main()
{
char
str[53];
int
i;
clrscr();
printf("\n
enter the string-");
gets(str);
i=0;
while(str[i]!='\0')
{
i++;
}
printf("\n
the length of string is- %d",i);
getch();
}
/*
Output
Enter the string-Maharashtra
The length of string is- 11 */
2) Write
a program to copy one string into another string
Student
Name:Tambe Sanjay Baban Roll No:153
Program
Name: Write a program
to copy one string into another string
#include<stdio.h>
#include<conio.h>
#include<string.h>
void main()
{
char str1[30],str2[35];
clrscr();
printf("\n Enter the first string-");
gets(str1);
printf("\n Enter the second
string-");
gets(str2);
strcpy(str1,str2);
printf("\n
The string after coping");
puts(str1);
getch();
}
/*
Output
Enter the first string-India
Enter the second string-Maharashtra
The string after coping Maharashtra */
3)Write a program to accept the string and display
it reverse
Student

Program
Name:Write a program to accept the string and
display it reverse string.
#include<stdio.h>
#include<conio.h>
void
main()
{
char
str[21];
int
i,j;
clrscr();
printf("\n
Enter the string-");
gets(str);
i=0;
while(str[i]!='\0')
{
i++;
}
i=i+1;
printf("\n The reverse string is-");
for(j=i;j>=0;j--)
{
printf("%c",str[j]);
}
getch();
}
/*Output
Enter the string-Maharashtra
The reverse string is-arthsatahaM */
4)Write
a program to accept the string and check whether it is palindrome or not.
Student
Name:Tambe
Sanjay Baban Roll No:153
Program
Name: Wap
to accept the string and check whether it is palindrome or not.
#include<stdio.h>
#include<conio.h>
void
main()
{
char
str[21];
int
i,j=0,temp=0;
clrscr();
printf("\n
Enter the string-");
gets(str);
i=0;
while(str[i]!='\0')
{
i++;
}
i--;
while(j!=i)
{
if(str[i]==str[j])
{
temp=1;
}
else
{
break;
}
j++;
i--;
}
if(temp==1)
{
printf("\n String is Palindrome");
}
else
{
printf("\n String is not Palindrome");
}
getch();
} /*
Output
Enter the string-madam Enter the string-India
String is
palindrome String is not palindrome */
5)1. Write
a menu driven program in 'c' which performs the following, operations on
string.
-check if one string is
substring of another string,
-count number of occurrences of
a character in the string,
-Exit.
