Consider my following code:

I have a string which contains some command line arguments for a calculator. What sort of argument it is can be determined by the first word in the string. For example:

#include <iostream> #include <string> using namespace std ; int main() { int t ; cin >> t ; int range ; cin >> range ; int counter = 0 ; while ( t– ) { int j = 0 ; string num ; cin >> num ; for ( char i : num ) { […]

I am trying to write a program in c that converts a string into a mathematical function to be used in my program. For example: the user will input x+3+7 as a string then the program will convert it to an equation that can be calculated.

i’ve wrote a small program to format a text file. So far i am mostly statisfied with the result of my program. What is unaccaptble is the time it needs to compile and execute. It takes 6 seconds to compile and even longer to execute. Is fgetc the problem?

I am a newbie in C. Consider my following code:

How can I improve this code and are there any situations where it won’t work?

#task:input a number “n” and a string ,then shift the string
1.example:
hello
2
output:
llohe
