Well what the title says, but I can't get it done. This is what I got
Code:
#include <stdio.h>#include <string.h>
int main(void)
{
char word;
int count;
printf("Enter a word.
[Code] ....
In this code, i declared a string constant and trying to print the length of string. I know that if i write char a1[7] or char a1[] than it runs and give aggregate output, but in this case it is giving double length of string.
Code:
#include<stdio.h>
#include<conio.h>
#include<string.h>
void main()
}
[code]....
I would like to understand a function on strings. Below is a code that I took from my teacher where the user inputs a string and prints out the length of the string.
Code:
#include <stdio.h>
#include <string.h>
int main() {
char str[100];
int i = 0;
[Code] ....
Now I understand that it returns the count in "int" so my question is:
Let's say i declared
Code: int count = 0;
at the beginning of the code and then made
Code: count = strlen(str);
why wouldn't i have the same result? Is there a way to do it also?
I want this program by using only iostream.h & conio.h

I was able to satisfy two or the requirements: to print all Pythagorean triples with the length of the hypotenuse being below the entered value and to state how many Pythagorean triples there are. I've come into a problem, though, since the final requirement is to state the largest Pythagorean triple. The problem is that it posts the values of a,b,c after the loop exits, which are going to be the values right below N (eg. N=19, then a,b,c=16,17,18).
Here is the program:
Code:
#include <stdio.h>
void main () {
int a,b,c,N;
int ctr = 0;
[Code] ....
My questions is how to fix this problem because putting it in the for loop will just cause it to repeat all values.
#include <iostream>
using namespace std;
int main()
{

how do i change this code to accept two numbers from the user and print it as the different length and widtth? it has to be a for loop as well.[code]
I'm trying to make a program in C where the user enters a string and it prints a word for example (name) in lowercase then the same word again but in capitals and lowercase like this (NnAaMmEe).
my code is below;
#include<stdio.h>
#include<ctype.h>
int main()

How to make it so an output for a program would print out the string in reverse/backwards? I was just curious on how to do this.
View 6 Replies View RelatedI wrote this program to scan a number and a string until EOF then print them to a file named "data.list". the problem is that the program duplicates last line of input in the output file. so for example if the input is :
1 test
2 dream
3 code
then output (in data.list file) would be:
1 test
2 dream
3 code
3 code
I also changed the program code so that it reads from data.list file. even here it duplicates last line!
so when program reads the info above saved in data.list it would be:
1 test
2 dream
3 code
3 code
3 code
here's the code for writing:
#include <stdio.h>
int main( void )
{
int num;
char str[80];
FILE *fPTR;
fPTR = fopen( "data.list", "w" ); // opens a file named "data.list", create if doesn't exist
while(!feof(stdin)) // loop until End-Of-File is pressed. Ctrl-Z in Windows, Ctrl-D in Unix, Linux, Mac OS X
[Code]...
and the one for reading from file:
#include <stdio.h>
#include <conio.h>
int main( void )
{
int num;
char str[80];
FILE *fPTR;
[Code]...
How do I fix this behavior??
I'm trying some codes about string arrays and taking array length. But i have some problems. I can't get length of string and can't send to a function.
------------------------
#include<iostream>
#include<cstring>
#include<string>
using namespace std;
void GetLength(string);
std::string Words[]={"table","gun","programming"};
int main()
{std::string InputWord;
[Code]...
And how can send Matrix to other function?
int t;
string a;
cin>>t;
getline(cin,a);
int len=a.length();
cout<<a<<" "<<len;
[code].....
why is the length 0?what can I do to get the correct length of the input string?
I can't find any method of retrieving the length of an array except for doing this:
string first[] = {"a","be","see"};
int length = sizeof(first)/sizeof(first[0])
This is a very unconventional way of getting the length of an array.
first->length() would return 1 because it returns the number of letters in the first element of the array (which actually makes no logical sense).
first.size() would return 1 aswell as it's practically the same thing.
Since getting the length of an array is such a fundamental feat, how come I can't find a decent method of doing it?
Is there no buildt in method for this? If there is not, why has it not been implemented in the std?
The input consists of one or more packets followed by a line containing only # that signals the end of the input. Each packet is on a line by itself, does not begin or end with a space, and contains from 1 to 255 characters.
it said 1 to 255 characters
i have to use getline(cin,str);
i tried str[255] but some error happen
I am stuck here.
printf(" Enter a line of Morse Code for decrypting");
scanf("%s",phr);
len=strlen(phr);
for(a=0;a<36;a++) {
if(strcmp(phr, morse[a])==0)
printf("%c", alpha[a]);
};printf(" ");
The output :
[output] Enter line to encrypt:
..... -.... --...
converting...
5 [/output]
It should read all code, including null. between coded letter one space, between coded word three spaces.
The output should be:
[output]
56 7 [/output]
consider the following code:
string input;
getline( std::cin, input )
In the code above, what is the maximum number of characters that can be read into variable input?
Any way to get the length of a string? I have tried:
str.length
str.size
strlen()

I manage to split this str = "abc,def,123"
to s1 = "abc", s2 = "def", s3 = "123" with this piece of code using find and substr.
string str, s1, s2, s3;
getline(cin, str);
unsigned pos1 = str.find(",");

But what should I do if the len of the string is unknown ?
For example, str = "abc,def,123,ghi,jkl,456,mno" and so on...

To make the function work better we change its internals

return null terminated string length

This phenomenon can be observed by use of mutibyte to wide char conversions, string copy , concatenation functions of MS etc ....
Should I minus one in the return value of the second function to match both versions ?
What I'm trying to do is to assign the length of a string to an integer variable. This is what i tried, it did not work.
Code:
printf("Enter a string
");
fgets(test_pass, 30, stdin);
strcpy(x,(strlen(test_pass)));
printf("%d", x);
This was just a test, and it did not compile. How to do this?
I want to read a string of unknown length from stdin. I tried to follow the approach from this link. URL....My code is like this:
#include <iostream>
#include <string>
using namespace std;
int n;
cin >> n;
cout << "The value of n is " << n << endl;
}
[code]......
What I have noticed is that if I take integer input from cin (cin >> n;) in the above code before getline, the control does not stop on getline to take str as input from the console. If I don't do (cin >> n) before getline then the control stops on getline and takes the string as input.What is the best way to read from console multiple strings of unknown length in combination with the integers?
The error is unclear but suggests Its received a bad pointer from another heap. It references dbgheap.c line 1322 and assertion failure
I have two string vector functions the first is called from the main function, the second is called from the first.
Their purpose is to receive a string of text and numbers in a semi-specific format, which the main body of the code reads from a text file, and delaminates the data as to return the first variable in the string as the variable name and the second as the variable value. Along the way it filters out a lot of the unwanted whitespace and punctuation.
E.g "{ VariableNameA 123 }" would be returned as "VariableNameA" And "123"
The code works perfectly for most of the lines in the text file but fails on one particular line where the first variable is 25 characters long. Basically it works for anything 22 characters or less. There are never more than 4 elements in the vector and each element is never intended to be longer than 25 characters.
It fails trying to return from the second split function to the first split function.
Is there a limit to the size of each vector element? I'm struggling to find a way round this without having to rewrite the whole thing.
vector<string> split(const string &s, char delim) {
vector<string> elems;
split(s, delim, elems);
return elems;
[Code] ....
I need to know if it is possible to show the maximum length that is defined a string. I explained it with a example
void charLong(char *a){
cout <<"a defined max long = "<<a-><FUNCTION>;
} int main() {
char str[40];
charLong(&str);
return 0;
}
That the result was : a defined max long = 40.
I know that exist strlen() but this show only the length that is used, I need the definition length. is it possible?
I have a question about finding the length of first sentence in an input string.
For example, let the input string be: dream in code. community learning
The length of first sentence is 13 (blanks are included). My question is how to create conditions for multiple punctuation signs (!,?)? If while loop goes like:
while((str[i]!='.')||(str[i]!='!')||(str[i]!='?'))
it gives me an error for infinite loop.
Code:
#include<stdio.h>
int main() {
char str[100];int i=0,br=0;
printf("enter a string:");
gets(str);
[Code] ....
1. Create a variable named index and nitialize it to zero(0)
2. Prompt for and input a string value from thekeyboard. Store the string inthe string variable newstring[80].
3. While (newstring[index] does not equal ‘ ’).
i. Display the character at newstring[index] followed by a NL
ii. Increment index ====================================== ...
And this is what i have done so far and i dont know where I am wrong ...
Code:
#include<stdio.h>
int main()
{
int index = 0; //initialize index to zero since first elementin an array is numbered zero
char newstring[80];

if you have something like this how can you print the string in main??

/#include <stdio.h>
#include <stdlib.h>
