In this program we are giving comment-line argument conversion to long long integer. Open Compiler #include <iostream> #include <string> using namespace std; int main(int argc, char * argv[]) { if (argc != 2) { cerr << "Usage: " << argv[0] << " <number>" << endl; return...
The syntax for the strtoll function in the C Language is:long long strtoll(const char *nptr, char **endptr, int base);Parameters or Argumentsnptr A pointer to a string to convert to a long integer. endptr It is used by the strtoll function to indicate where the conversion stopped. The...
long int strtol(const char *nptr, char **endptr, int base)Note: If the value passed for conversion is too small or too large, then it will store ERANGE in errno. If the value is too large, then it will return a value of LONG_MAX. If the value is too small, then it will retu...
Long.valueOf(String):Converts the String to a long value. Similar toparseLong(String)method, this method also allows minus ‘-‘ as a first character in the String. publicclassJavaExample{publicstaticvoidmain(String[]args){Stringstr="11111";Stringstr2="88888";try{//Conversion using valueOf...

In this guide, we will discuss the following ways to convert a long value to a String: String.valueOf(long l) Method Long.toString(long l) Method String.format() Method Using DecimalFormat Using StringBuilder and StringBuffer Note: Out of all these ways,

The pointer to the converted characters, even if conversion was unsuccessful, is stored in the object pointed to by endptr, as long as endptr is not a NULL pointer.Returned value If successful, strtol() returns the converted long int value. If unsuccessful, strtol() returns 0 if no conver...
