atoi and iota seem like perfect partners. atoi is the ‘ascii to integer’ function and itoa is the reverse, the ‘integer to ascii’ function. You would use atoi to convert a string, say, “23557” to the actual integer 23557. Similarly, you would use itoa to convert an integer, say 44711, to the equivalent string “44711”. Very handy.

Command line arguments in C and C++. command line arguments and atoi. You can pass an executable command line arguments when you run it like the C LIBRARY FUNCTIONS->Detailed Descriptions->atoi() atol() atof()atolf() These functions convert a character string to an integer value (atoi()), a long integer Purpose. Converts a string to a signed or unsigned long integer or long long integer.
When using the function, remember - the function returns the first valid number that can be converted from the received string. If no number can be converted whatsoever, it returns 0. C Language Convert Strings to Number: atoi(), atof() (dangerous, don't use them) Example Warning: The functions atoi , atol , atoll and atof are inherently unsafe, because: If the value of the result cannot be represented, the behavior is undefined. The atoi () function converts the initial portion of the string pointed to by nptr to int.

Use more robust and reliable strtol() function to convert string to integer.
