Write a C function that defines two strings as parameters, as follows, and checks whether the second string (str2) is a substring of the first one (str1).

Posted by Tushar Bedekar



int substring_finder(char* str1, char* str2);
The function should return an integer as follows:
• 2 if str2 is a substring of str1 and also of same length
o e.g. str1 = "Hello" and str2= "Hello"
• 1 if str2 is a substring of str1 and of different lengths
o e.g. str1 = "Hello World" and str2= "Hello"
• 0 if str2 is not a substring of str1
o e.g. str1 = "Hello" and str2= "Helo"


 

program me starts from here:-

#include(string.h)                                         //  note place '<' & '>' in place of '(' & ')'
#include(stdio.h)
int substring_finder(char *,char *);

Write C programs that use both recursive and non-recursive functions to find the factorial of a given integer.

(a).without using recursive function.

#include(conio.h)
int fact( int);                                        // function declaration
int main( )
{
int no,result;
clrscr( );
printf("Enter the required number:");
scanf("%d", &no);
result = fact( no);
printf("\n %d Factorial is : %d", no, result);
getch( );
return 0;
}
int fact(int n)
{
int ft,
for( ft=1; n>=1; n--)
ft=ft*n;
return ft;
}

Output:- 4 Factorial is : 24

(b).using recursive function.

C MAGICAL PROGRAM ME:-

Posted by Tushar Bedekar


void main()
{
int a;
a=300*300/300;
printf(“%d”,a);
}
What will be the output of the above Program

Few options which I can give are -

(1)300
(2)1
(3)81
(4)600
The Correct answer for this question is -

Option 3 i.e. 81

Confused???????

Check here



In C integer has range from -32768 to 32767.
Hence          32767 + 1 = -32768
Similarly       32767 + 3 = -32766

For the above question

300*300=90000

The value stored in integer variable ‘a’ is 24300

Now 24300/300 = 81 



Hence the answer is 81

Turbo C + + is a C + + compiler with an integrated IDE that was developed by Borland, known because its speed in compilation and linking. This product is part of the family Borland compilers that is very popular  including Turbo Pascal, Turbo Basic, Turbo Prolog and Turbo C. Turbo C + + is a successor of Turbo C which is a further development with uniformity of procedure in the compiler as well as the manner contained in the Turbo Pascal 5.5 adding object functionality in Turbo Pascal versions previously. But unlike the Turbo Pascal, Turbo C + + always follow and maintain the standards that apply to C + + language.
