If you have any questions, contact us. -- Linux general technology-Linux programming and kernel information. The following is a detailed description. Today, when I want to write a resume for creating a txt version under the character terminal, I encountered a problem, that is, the process of converting the numeric string into an integer number. I found many places on the Internet, I don't know if such a library function is available in linux. Can anyone tell me?

(There is no way to write one on your own at last, but it is quite helpful. Please give me more criticism !)

Int converse (char * p)
{
Int I, j;
Int integer, result = 0;
Int length = strlen (p );
Int temp = length-1;

For (I = 0; I {
Integer = 1;
For (j = temp; j> 0; j --)
{Integer * = 10 ;}
Temp --;
Result + = (p -'0') * integer;
}

Return result;
}
Int main (int argc, char * argv [])
{
Int m;
M = converse (argv [1]);
Printf ("the result is: % d \ n", m );
Return 0;
