There is a very wellknown algorithm (created by Robert W. Floyd).This algorithm is called Floyd's cycle finding algorithm.It uses 2 pointers moving at different speeds to walk the linked list. Onc...

There's an algorithm called Floyd-cycle finding algorithm.Briefly, start from a node and traverse the list in steps of one and two using two pointers. Eventually, both the pointers will coincide if there exists a cycle in the linked list.

strcat(buf,buf);
printf(buf);
}
While executing this in VC++ I do not get an output . Looks like the program runs into an infinite loop. But while executing the same in Turbo C I get the output as "hellohelloh". What could be the reason behind this difference in output?">Consider the following program segment :#include #include void main () { char buf[100] = "hello"; strcat(buf,buf); printf(buf);}While executing this in VC++ I do not get an output .

As kbjarneson pointed out, the problem is that you are clobbering the 0 terminator of the input string; once that happens, strcat() doesn't know where to stop. His solution is to use memmove...

Hi frns the above one ans is cbecause a1 can hold only the value of s1 but not its address value........abd more over p1 cant be hold by a1 so the a1 cant become pointer to p1

Write code sample for string reversal program in c by using for loop and using only one buffer
jbode

Below is a simple, straightforward, maybe not the fastest method for reversing a string in place. Why not start j at strlen(str) - 1? If the string is empty, strlen will return 0, and since size_t...

We can use directly strrev ()
Code- #include <string.h>
- #include <stdio.h>
- "string""Before strrev(): %s

Pointer to an Array
What is pointer to an array? Explain with example.
jbode

For any given data type T, a pointer to an array of T is declared as "T (*arr)[N];". It has the same value as a pointer to the first element of the array, but a different type (T (*)[N...

How do you redirect a standard stream?
Most operating systems, including DOS, provide a means to redirect program input and output to and from different devices. This means that rather than your program output (stdout) going to the screen; it can be redirected to a file or printer port. Similarly, your program’s input (stdin) can come from a file rather than the keyboard. In DOS, this task is accomplished using the redirection characters,...

By using the operators "" we can redirect the standard input and out streams.example : d:> jinto.exe > outputredirected d:> jinto.exe < inputredirected

I think that C doesn't define any opeartor for exponential function. It rather provides us with a pow(number, number_to_the_power) function that helps us to do the exponential opearations.

Unbelievably, there is no built-in exponentiation operator in C. Instead, there is a library function (pow) which carries out this operation.

First of all, you can clean up that malloc call (see attached code). You shouldn't cast the result of malloc; its unnecessary, and under compilers that use the 1989/1990 standard, it can suppress a d...

Lint is 1. a C compiler 2. an inter-active debugger 3. a C interpreter 4. a tool for analyzing a C program

Lint was the name given to a tool flagged suspicious and non-portable constructs (ie, likely to be bugs) in C language source code. Ans is 4} tool for analysing c program

I think ans is 4, as? this is used for analysing source code, However it can be used for flagging bugs
Which of the following is not an infinite loop?A. while(1){ ....}B. for(;;){...}C. x=0; do{ /*x unaltered within the loop*/ .....}while(x = = 0);D. # define TRUE 0 ... while(TRUE){ ....}

It is not c) becoz in while loop comparision takes place that is 0==0(which is true and returns the value 1) so while loop executes and it goes in infinite loop. The correct answer is (D) becoz in while loop condition becomes false with zero(0) and never enters into the loop.
If the following program (myprog) is run from the command line as myprog 1 2 3, What would be the output? main(int argc, char *argv[]) { int i,j=0; for(i=0;i<argc;i++) j=j+ atoi(argv[i]); printf("%d",j); } a) 1 2 3 b) 6 c) error d) "123"

Ans is 6.atoi is the function which return the decimal or digits in string.

B) 6atoi fails on the first element of argv[], being "command.exe", but atoi returns 0 in case of failure.

C++ also support structure bt with more additional features making it suitable for oop dat feature is class. like in c++ enum defined within class/structure is local to dat class while in c it is globally visible
