Write a c program to print the answer of a task which is given as a single string as a value?

for eg:- if we give 5+3 as an expression the output should be 8


that is sum of the given expression


not by reading each character into one variable.


the input should be into one single string

Do u know, in c++ programming, how I can infile a string which has exactly n characters in it? I appreciate it

If you use fopen for the stream you could do an fread to read a specific number of bytes from the stream.

C++ code to replace words in a document, keep getting run error?
Telling us what Run Error you're getting might help. Besides the fact that you don't even say what compiler you're using, few people here want to take the time to cut-and-paste all your code into our compiler, then work through getting it to compile and start running to find out what it MIGHT be.





Sorry that's not directly helpful, but it's good advice.
Reply:hey dude, u missing some semicolons maybe. at least i spot one.

How to write C program for finding reverse of a string?

How to write C program for finding reverse of a string?
this sounds like homework, so I'll just give you an idea.





put the string in an array.





ie "string"





s[0] = 's'


s[1] = 't'


s[2] = 'r'


s[3] = 'i'


s[4] = 'n'


s[5] = 'g'





make a variable, say x, the size of the array. output the string backwards, starting from x while x %26gt;= 0.





5 - g


4 - n


3 - i


2 - r


1 - t


0 - s

Write a c++ program that convert numeric value to string?

for example:


input: 190.65


output:one hundred ninety and sixty five

Write a c++ program that convert numeric value to string?
Step 1: Convert floating point number to a string using these samples


http://www.cprogramming.com/tips/showTip...


http://www.codeguru.com/forum/showthread...





i.e., 190.65 to





convertedStr = "190.65";





Step 2: Have an array of strings like


text[0] = "";


text[1] = "one";


text[2] = "two";


text[3] = "three";





and lookup for each char in the converted string:





if(convertedStr[0] == '1') output = text[1];
