Fundamentals
Strings
Data Types
You will be given a number of minutes. Your task is to return a string on the heap that formats the number into 'hours:minutes".
Make sure you always return two integers for the minutes section of the conversion.
i.e. ('0:01' instead of '0:1')
Example:
minutes(90) => '1:30'
char *minutes(int num){ char *ret = calloc(64, sizeof(char)); sprintf(ret, "%d:%02d", (num / 60), (num % 60)); return ret; }function minutes(num){return num % 60 < 10 ? Math.floor(num/60) + ':' + '0' + (num % 60) : Math.floor(num/60) + ':' + (num % 60)- char *minutes(int num){
- char *ret = calloc(64, sizeof(char));
- sprintf(ret, "%d:%02d", (num / 60), (num % 60));
- return ret;
