c++ - Convert a String to an int and store the result in a variable -


int units;

void input(int i) {     char temp[50];     printf("enter class id #%d > ", + 1);     readline(classid);           printf("enter name #%d > ", + 1);     readline(classname);             printf("enter description #%d > ", + 1);     readline(description);           printf("enter pre-reqs #%d > ", + 1);     readline(prereqs);     printf("enter units > ");     readline(temp);     // write method convert string temp integer , store in units field

i think need nested loop not sure how go conversion please help.

use atoi() function cstdlib (you need include cstdlib @ top of file):

units = atoi(temp);

it converts char array integer. see here.

you can use strtol() allows error checking, see here details. credit: @nathanoliver
