C语言规定,**不同类型的数据(比如char和int型数据)需要转换成同一类型后,才可进行计算。**如果你混合使用类型,比如用char类型数据和int类型数据做减法,C使用一个规则集合来自动(隐式的)完成类型转换。这可能很方便,但也很危险。 这就要求我们理解这个转换规则并且能应用到程序中去! 当出现在表达式里时,有符号和...

One method to convert an int to a char array is to use sprintf() or snprintf(). This function can be used to combine a number of variables into one, using the same formatting controls as fprintf(). The prototypes: #include <stdio.h>int sprintf ( char *buf, const char *format, .....
A string is nothing but an array of characters. The value of a string is determined by the terminating character. Its value is considered to be 0. As it is evident with the image uploaded above, we need to enter both the strings which we need to concatenate or link. ...
