I understand that the strrchr function is supposed to search for a string from the reverse. Unfortunately, mine isn't doing that.

int main() {
char userinput[100] = "null";
char searchchar;

I am new to C and trying to reverse a string but the function is not getting called.. the console says :
Enter a stringabhi
bash: line 1: 229 Segmentation fault (core dumped) ./program
Code:
#include<stdio.h>
#include<math.h>
#include<string.h>
char* reverseString(char input[]);
void main()
[Code] ....
Here's my program: - Program which inputs a string from user, reverses it and displays it.
#include <iostream>
using namespace std;
void string_reverse (char [], const int);
int main() {
const int arraysize = 10;
char string[arraysize];
[Code] ....
In the string_reverse function, I have declared temp character type array but on line 38, the
compiler is throwing 3 errors: -
error C2057: expected constant expression
error C2466: cannot allocate an array of constant size 0
error C2133: 'temp' : unknown size
I have declared a constant integer arraysize in line 35. Now I have no clue why is this happening because I think as I have declared it as a constant integer variable, this should not happen.
Code:
#include<stdio.h>
#include<string.h>
#define MAX 25
int main(void)
{
int ch;
[Code]....
i think that cause this program to be error.because when i using the reference from internet, the program was executed for sure.This code what i mean
Code:
#include <stdio.h>
#include <string.h>
#define MAX 10
int main () {
int ch;
char str[] ="This is a simple string";
char str1[MAX];
char str2[MAX];
[Code]....
and rather than that i didnt have anymore idea to make that replacing string.
I currently have a file which allows inputs to record different transistor types. I then have the task of accessing this structure, find a certain manufacturer ID, and print the information about this particular transistor.
My problem is accessing the array to search through.
Here is my code:
Code:
#include "stdio.h"
const int IDLEN=30; //All constant values defined
const int POLARITYLEN=3;
const int MAXSTOCKITEMS=10;
//First structure defined
struct TransistorRec {
[Code]......
The errors I am currently getting are on line 54 'expected primary-expression before "struct"' and on line 60 ' 'maunfacturersID' undeclared'
I made a simple little program that takes text from the clipboard, and spits out all the lines I've copied one at a time (so my program can analyze it).
everything works perfectly, except, it spits it own in the wrong order, I want it to spit out from bottom to top. but currently it spits out the data from top to bottom. here is my code :
Code:
#include <iostream>
#include <Windows.h>
#include <string>
#include <sstream>
using namespace std;
int main() {
HANDLE clip; // assigns the var. clip to hold a handle ID.

I want this loop to run backwards! Like it say's what I want to work backwards. Where as I know how to flip a while loop like this: while(x < 5), how to flip a loop like the one I'm using. how I can do this?
If I am executing following code after reversing it is giving "1" but I need "0001".

reverse = reverse * 10;

I was browsing the web looking for simple yet fun programming challenges and crossed this one. I figured out how to reverse the string in place but I want it to read "blue is house the". I approached it in two ways for the heck of it. My idea was the second one, the first one I googled. I didn't know a simple rbegin() could do that, pretty neat.
I found the question here.[URL] ....
Code:
#include <iostream>
#include <string>
int main(int argc, const char * argv[])

std::string phrase = "The house is blue.";

I have written a function that inserts and prints a binary function correctly.
For example a tree like this [URL] ..... would print like this
Code:
node: 10
node: 7
node: 6
node: 8
node: 9

Here is my print function
Code:
void prt_tree(struct node *tree) {
if (tree == NULL) {
printf("Null Tree

return;

Could I just make some adjustments to my function to reverse it? and if so, how?
Here's what I have to do: Using strcpy() pass it two strings of characters (such as a name like John Johnson) and copy the second string into the first, in reverse order, and print both. Write a main to exercise your function and to illustrate that the function is working properly.

I'm trying to reverse every even word in a string (not all of it). But I keep getting an empty output.

The mouse was caught in peg.
The esmou was thgauc in gep.

How do reverse every alternate words in a string that I read into my program:
e.g. The mouse was caught in a clothes peg.
reversed (including the full stop)
The esoum was thguac in a clothes gep.
I could program it to reverse the whole sentence. But no clue how to reverse certain words such as every even word. Do I need a function and/or loop to solve this?
#include<iostream> // allow input and output
#include<string> // allow for larger entries of characters
using namespace std;
int main() {

I am supposed to take the three string lines from a text file and then individually reverse them and state whether or not they are a palindrome. I have the three lines from the text file into string variables already but I am not sure on how to reverse them and then see if they are the same reversed(palindrome)
Here is my code so far -->
#include <iostream>

I noticed that when using variadic functions, if I pass the va_arg() as parameter to a function, the parameters get passed in reverse. Is that expected?
For example, the following code outputs
Code:
1 2
2 1
Code:
#include <iostream>
#include <stdarg.h>
void foo_func(int v1, int v2)
{
std::cout << v1 << " " << v2 << std::endl;

I have code for conversion of longitude and latitude and I need to reverse the function so it will work in opposite direction:
Code:
float LongitudeDeg = argv[1]; // some longitude
float LatitudeDeg = argv[2]; // some latitude
uint32_t u,v,l,n;
l=15; // l range is 2-29
[Code] .....
On start of the code we know longitude,latitude and l. And the result is u and v. And I need function when I will know the u and v, possibly l too, to calculate longitude, latitude.
I should state that I am recently new to C programming. I have dabbled with Python in the past, but nothing formal. I am taking a C programming class, but it is an introductory course. As such, the instructor is moving extremely slow through the material.
With this program, I am trying to search a given text file (line-by-line) for user-submitted data. I then want to be able to store which line that data was found on. The program runs, but it always results in "Sorry, couldn't find a match." Even if it shouldn't.
Code:
#include <stdio.h>
#include <conio.h>
#include <string.h>
#include <stdlib.h>
}

I should probably explain my overall goal with this program.I would like to write a program that will calculate the molecular weight of a compound. I expect the user entered molecular compound to be something like this: CH3COOH (An equivalent entry could be C2H4O2)Also, it needs to be case sensitive because the chemical formulas are case sensitive.
The output will be "The molecular weight of CH3COOH is xxx.xxxxx grams".I have two text files as well. One contains a list of all chemical symbols, and the second is a list of all atomic weights in the same order as the first. I want to place the user inputted data into an array, then search for each element of that array in the chemical symbol text file. It will show which line it was found on, then I can use that line to grab the atomic weight from the second text file.
i have a work to do that consists on a given char pointer to a chain and a also given char pointer to a string. i have to search that chain in the string, and return the position where the beginning of the two it's equal. but only if they are equal.
example: string is "abcd" and the chain is "bc". want to find the chain, and if it exists, the position return will be 2. in the work it says that we should use sprintf() too. here is my code, which is incomplet yet.
Code:
char* pos(char* C,char* S){
char *str = S;
char *chain = C;
int i, j, temp;
int lengthStr = strlength(C);
int lengthChain = strlength(S);
}
[code]....
my doubt is how to use sprintf() and where. if i have to use malloc() and free(),
other examples:
pos(AGA,CTGCA)
return:
0
pos(AGA, ATAGATA)
return:
3
pos(AGA AGATAGA)
return
1 5
