C :: Count Lines In Input And Display Output In Terminal When Program Executed After Compilation
Feb 4, 2013
Code:
#include <stdio.h>
main() {
int c, n1;
n1 = 0;
while ((c = getchar()) != EOF)
if (c == '')
++n1;
printf("%d", n1);
}
I have a more complicated program I'm wishing to have display the output, however, to save some time I'm using an example of a shorter version. count the lines in input and display the output in terminal when ./program is executed after compilation. To count and compute lines, words and within arrays.
My program does compile and counts the number of lines of code, which is LOC: 20. My issue this, according to my code instruction it should not count comments (//) and also shouldn't count blank lines of code. Unfortunately my code is counting // and white space.
What seems to be working is #, all three includes are not being counted. That’s a good sign. I’m using the same technique not to count #. Why isn't working for comments and blank lines? I’m pretty sure that my logic is correct. I think my problem is maybe syntax.
#include <iostream> #include <fstream> #include <string> using namespace std; int main() { //read my file
I have a .txt file that contains, together with a few characters, columns of values that I want to save in different files like is written in the program (file 1, file2, file3 - a with x, b with y, c with z). The pattern of the source text file is like this:
Until now I could manage to split the files, but the output gives me only zeros. First the program count the number of lines of the read text file, then it should display the desired columns of double values in three other .txt files.I've got for the three .txt files columns like this:
I'm making some progress. My program does compile and output the number of line per code, but it shouldn't count comments and blank lines. I tried using (s.substr(0,2) == "//") as suggested but it didn't work.
This is my improved code:
Code: #include <iostream> #include <fstream> #include <string> using namespace std; const int A = 3; int main() { string s;
I'm trying to code a program to read the user's input and have it:
-count vowels -stop counting vowels after '.' or '?' (ie. abcdjwef is 1 a, 1 e; while fje.fwdfeiii is just 1 e) -closes when ENTER is pressed after a '.' or '?' is found (ie. closes after 'abacds. ENTER' as well as 'as.fefsdf ENTER') -display the number of vowels
Is there any way to do this with only 'cin >> userInput' and a while loop checking for punctuation?
I have program that is supposed to read in a story from an input file and separate the words and output the lines on which the word occurs. It needs to read in another input file that has a list of words (1 per line) to ignore. i.e. skip them when running through the story. This is what I have so far, I've changed multiple things trying to get it running....
#include <stdio.h> /* function that will identify if line is empty or not */ is_empty(char *buffer) { while(isspace(*buffer)) buffer++; if(*buffer==0x00) return 1;
So I am writing a program that counts the letters of 3 lines of input from the user. I am using a 3 x 80 character array as the "notepad". Upper and lower case characters are incremented on the same counter array.
Code:
/*Letters in a string*/ #include <stdio.h> #include <string.h> #include <ctype.h> void countAlphabet(char *); /*Character counting array*/ int alphabet[26] = {0};
4.1 Write a program that will count from 1 to 12 and print the count, and its square, for each count.
4.2 Write a program that counts from 1 to 12 and prints the count and its inversion to 5 decimal places for each count. This will require a floating point number.
4.3 Write a program that will count from 1 to 100 and print only those values between 32 and 39, one to a line. Use the incrementing operator for this program.
I need a way to count lines in a .dat file using fscanf. I must use a regex to check that the characters in the file are alphanumeric. In essence I need to count the ' ' character. I know fscanf ignores this character. I need to exit if it detects anything other than alphanumeric with the digit that is "problem" along with the line number. My .dat file is:
Code: howard jim dave joe ( Maggie My fileCheck.c is: Code: #include "main.h" int fileCheck(FILE *fp) { int ret_val; int line_count = 0; char file[BUFF];
[Code]...
The output I am getting is:
Code: file opened Digit: ( is not an alphanumeric character on line: 5 Program will exit! File closed As you can see, the character "(" is not on the 5th line but the 3rd. It is the 5th "string."
In above XMl if you check the ParentProductCat is prefixed with ns1:,ns2:,ns3:....
My XSLT code only checkes for the ParentProductCat but since it is prefixed with "ns*:" (* is integer) it fails to find it. So that in C# code replace function is used to replace ns*: a for loop is used for this and it goes until 1000
But now my response crossed the 1000 mark and this time the XML contains total 14500 lines.So I want to replace all ns:*
For this I want to count the number of lines present in the XML so that the for loop will run until that line number. how to do that?
The code is supposed to display the total and averages of the data as well, but cuts off due to an error in the code. The code should also:
1)Print checks for all employees, one per page, sorted by lastname. The first check number, 100, is to be read from a company data file (see requirement 4). The border of each check is important and should not be omitted.
2)Convert the net pay to a text string for each check printed.
3)Print a reference code on each check. The reference code is obtained by combining the first letter of the lastname with all the consonants remaining after removing all vowels (a,e,i,o,u).
4)Use the same employee data found in assignment 2. Use company data, obtained from a text file, for each check printed:
im trying to write a program that prompts the user to enter three numbers and then prints them vertically (each on one line), first forward and then reversed. this is how the design should look:
enter three numbers: 1 43 54
your numbers fowards:
1 43 54
your numbers backwards:
54 43 1
this is what i have thus far when it comes to code....
#include <stdio> int main (void) { // local declarations int a; int b; int c
I wanted to make the terminal screen bigger in my NCurses program. Let's say if the defaults are 25 LINES and 80 COLS, I want to set them to 40 LINES and 120 COLS.
I've tried resizing all windows, but that did not work, because the actual terminal (console) was not resized. Then I found functions resizeterm and newterm, but they did not work. As far as my understanding goes resizeterm only updates NCurses information with the current configuration, while the window itself is not actually modified.
NCurses man page wrote:The function resizeterm resizes the standard and current windows to the specified dimensions
If I haven't made myself clear ( I sometimes make a mess of things... ), another example would be that I want my program to be fullscreen when I start it. Is this possible? It should be, I found a fullscreen NCurses program once, but the code was too confusing for me to understand.
Having read about things like SIGWINCH, I assume you must define a method for resizing the terminal screen yourself, I don't know where to start?
The problem that I am having is that , the program outputs numbers that are perfect numbers and im not sure where i can add a statement to make it so that if it isn't a perfect number it doesn't output...

In my class we were supposed to write a program from the book that inputted the names and votes and the program is supposed to spit out who won the vote. I did this then while i was reading the assignment from the instructor I noticed he wanted the information inputted from a TXT file instead of manually inputting it. I cannot seem to get it to work....

Prompt the user to enter a day of the week as M (or m), T, W, R, F, S, and U for Monday through Sunday respectively. The user may enter an upper or lower case letter.
When the user enters a character, the program will echo the letter and output the name of the day of the week.
Provide an error trap that reads something like "you have entered an invalid letter; program aborting." Suggestion: use a switch statement with the error trap as the default condition. it is not necessary to prompt for multiple inputs.
So I know how to get the program to echo back the letter and everything. What I am a little confused about is: will I have to define all the letters as their respective day? eg. make M== Monday. And if I do have to do that how would I get it to accept Upper and Lower case letters and recognize that that letter is == monday ect. ect.
Also my main problem is the switch statement as the error trap. I have never used the switch statement, but I know what they do. I just don't really understand how I would use it for an error trap. Am I suppose to just make a case for every other letter in the alphabet other then M T W R F S and U? Even if I do that then what if the user enters a number instead of a letter?
I am doing a written lab in my programming class in which we must write the output for three lines in a function. However, when I enter the code in my compiler I only get error messages. I was just wondering what the outputs under snap, crackle and pop should be and why.
#include <iostream> using namespace std; void snap (int i, int j); void crackle (int &a, int &B)/>; void pop (int &e, int f); int main () { int i = 1, j = 2;

what is the effect on output of program of different numbers input to the int data type named seed*/
I'm trying to write a code that displays lines between user designated points with circles at each point, but I can't get the lines to display! I'm at a loss on what to do and need fresh eyes on the subject.
#include <iostream> #include "graph1.h" using namespace std; //Function Prototypes Follow void getNoPoints(int* no_points); void getPoints(int* x, int* y,int no_points); void drawPolyLine(int* x, int* y, int no_points,int objects[]);
[Code] ....
I imagine the error is in this segment:
int i=0; for (i = 0; i < no_points;) { objects[i] = drawLine(x[i],y[i],x[++i],y[++i],1); setColor(objects[i],255,255,0); }
I run the program with gdb , i searched but find nothing about how i could run gdb , that shows what line of code is running constantly (i rather it also shows value of the variable on each line if it's possible ) without stopping (i mean i don't want to enter "step" every time , i just need to run the program with debugger and shows line of the code is running (without need to enter step each time by myself)is it possible? if yes , what command is needed to start gdb for this purpose?
P.S: for this purpose if i have to set breakpint i will. but even i rather not set breakpoint , i rather gdb while running the program shows what line is now executing (rather with the value of variabels).
