"Foreword" in the Linux embedded development which I have contacted, mostly uses the C language, uses the makefile file to compile the source file to build the executable file. This article describes how a small C project can write makefile

The C language can actually be understood as saving two data types, integers and floating-point numbers (bool type char types can be considered integer types).But this time not from two aspects, but the char type and so on from the integer type

Outputs a diamond graph.Solution: Program:#include int main (){int I, J;Char Diamond[][5] = {{', ' ', ' ' * '},{', ' * ', ' ', ' * '},{' * ', ' ', ' ', ' ', ' * '},{', ' * ', ' ', ' * '},{', ', '} 'Diamond Diamond, diamonds, diamondfor (i = 0; i

There are 3 strings to find the largest of them. Solution: Program:#include #include int main (){Char str[3][20];Char string[20];int i;for (i = 0; i {Gets (Str[i]);}if (strcmp (str[0],str[1]) >0){strcpy (String,str[0]);}Else{strcpy (String, str[1]);}
