          14. char name[5]=”apple”.strlen(name) =   5  

          15. char a[5]=”hEllo”.strupr(a)=   HELLO

          16.char b[3]=”HaI”.strlwr(b)=   hai  

17.char s1[5]=”hello”;char  s2[5]=”world”.strcat(s1,s2)=   hello world

18.char s[7]=”welcome”.strrev(s)=  emoclew

19. s1=”happy”.strcpy(s2,s1)=   happy 

20.s1=”hello”.s1 is Palindrome.[T/F].    False

21.Array index starts from   0  index

 

Answer the following Question

                                                                             (4 marks)

          1.Write a program for single dimensional array.

#include<stdio.h>

#include<conio.h>

main()

{

int a[5],i;

clrscr();

for(i=0;i<5;i++)

{

scanf("%d",&a[i]);

}

for(i=0;i<5;i++)

{

printf("\n %d",a[i]);

}

getch();

}

          2.Write a program to convert a word into lower case and upper case using String Function

#include<stdio.h>

#include<conio.h>

#include<string.h>

main()

{

char name[30];

clrscr();

printf("Enter your name:");

gets(name);

printf("The Uppercase string is:%s\n",strupr(name));

printf("the Lowercase string is:%s",strlwr(name));

getch();

}

          3.Write a program for strlen() and strrev() function using string

^{#include<stdio.h>}

#include<conio.h>

^{#include<string.h>}

^main()

^{

^{char name[30];}

^{int len;}

^clrscr();

^{printf("Enter your name:");}

^gets(name);

^{len=strlen(name);}

^{strrev(name);}

^{printf("The length of the string is:%d\n",len);}

^{printf("The reversed string is:%s",name);}

^getch();

^}

 

Answer the following Question

                                                                                      (10 marks)

1.What is Array?Write a program for Multidimensional Array?

Array is a collection of similar data type stored in continuous Memory location.

#include<stdio.h>

#include<conio.h>

main(){

int i,j,a[2][2];

clrscr();

printf("Enter the values \n");

for(i=0;i<2;i++){

for(j=0;j<2;j++){

scanf("%d",&a[i][j]);

}

}

printf("\n Matrix a \n");

for(i=0;i<2;i++){

for(j=0;j<2;j++){

printf("%d\t",a[i][j]);

}

printf("\n");

}

getch();

}

2. Write a Program for String Palindrome using string function strcpy(),strcmp(),strrev().

^{#include<stdio.h>}

#include<conio.h>

^{#include<string.h>}

^main()

^{

^{char name[30],string[30],reverse[30];}

^clrscr();

^{printf("Enter your name:");}

^gets(name);

^{strcpy(string,name);}

^gets(name);

^{strcpy(string,name);}

^{strcpy(reverse,strrev(name));}

^{if(strcmp(string,reverse)==0)}

^{

^{printf("the string %s is Palindrome",string);}

^}

^else

^{

^{printf("the string%s is not Palindrome",string);}

^}

^getch();

^}

3.Write a program for strcat(),strstr(),strchr() function using string

 #include<stdio.h>

#include<conio.h>

#include<string.h>

main()

{

char s1[30],s2[30];

clrscr();

printf("enter the string:");

gets(s1);

printf("Enter the sring:");

gets(s2);

strcat(s1,s2);

if(strchr("Hello",'e'))

{

printf("e is in hello\n");

}

else{

printf("e is not in hello\n");

}

if(strstr(hai everybody","hai"))

{

printf("found hai\n");

}

else

{

printf("Not found hai\n");

}

printf("the concatenated string is:%s\n",s1);

getch();

}
