C

... a programming language to follow B. C is the core language of Unix and later GNU/Linux and the liberation of it's compiler software, gcc (or the Gnu's Not Unix C Compiler), a foundation of the Free Software movement.

Variables

Variables in C are strictly typed meaning they always are one particular kind of representation of information (an integer number, a character, a string of text).

Strings

Strings in C are arrays of characters. Abstractly a string in C is simply a pointer; that is, a numeric memory location pointing to the first character of the text in the memory.

char text[] = "pioneering jazz electronic organ recordings";

int textlen = strlen(text);
for (var i=0; i<textlen; i++) {
    printf("");
}

Loops

Like, Bash, C has a for loop:

for (var i=0; i<10; i++) {
    printf("Hello %d" % i);
}
