Number Conversion

• To convert between strings and numbers use atoi and atof

  • int atoi(char str[ ]);
  • double atof(char str[ ]);

• If str does not correspond to an integer/double value then 0/0.0 is returned

• Need to include the cstdlib library (#include <cstdlib>)

• Example:

int num;

char str[ ] = “1234”;

num = atoi(str);
