Wow Ive just discovered your channel! You're an amazing teacher!! So What about if my str is something like "123Abetc" How can I separate the int part from the char part to evaluate them separately? Ive read strtol can accomplish this but I haven't figured out how yet! Thank you very much!
Yes, you can use strtol to separate the two. Here's a code snippet: char str[] = "123ABetc"; char strPart[100]; char* endPtr; long int numPart = strtol(str, &endPtr, 10); // numPart will be 123 // Here endPtr will point to the first letter in the str string. printf("%s ", endPtr); // Would print just the string part from the original string strcpy(strPart, endPtr); // strPart will be "ABetc", this will save the remamining string to another location (in strPart) which you can freely modify At the end: numPart will have the value 123 strPart will have the value "ABetc" And thanks for the support, it is much appreciated!
Hey ! Thank you for the vids ! Can you show me how to make a header or a file , where I can have commonly used funtions stored , for example , to use them faster when I need them . So , just to include the header , in use whatever function I need .
YOU ARE A GENIOUS!!! been trying to find out how to validate numbers when a user inputs a no number value, this is simple and works just fine!!!
Bro, thanks for your channel!!! Now I will sucessed on algorithms in college. Keep with your great work

char str[] = "123ABetc";
char strPart[100];
char* endPtr;
long int numPart = strtol(str, &endPtr, 10); // numPart will be 123
// Here endPtr will point to the first letter in the str string.
printf("%s
", endPtr); // Would print just the string part from the original string
strcpy(strPart, endPtr); // strPart will be "ABetc", this will save the remamining string to another location (in strPart) which you can freely modify
At the end:
numPart will have the value 123
strPart will have the value "ABetc"
And thanks for the support, it is much appreciated!
Greta video; great explanation. Much better than the man pages in UNIX. Cheers mate

Sure thing, I can make a video on that. Expect it next week.
Thank you for the video. What about real numbers how to validate 123.45 ?
Try using strtof or strtod: www.cplusplus.com/reference/cstdlib/strtod/
Basically the same as strtol but for real numbers
thanks
