Editing For loop (section)

===1972: C, C++===
{{Further|C (programming language)|C++|C syntax#Iteration statements}}
<syntaxhighlight lang="c">
for (initialization; condition; increment/decrement)
    statement
</syntaxhighlight>
The {{mono|statement}} is often a block statement; an example of this would be:
<syntaxhighlight lang="c">
//Using for-loops to add numbers 1 - 5
int sum = 0;
for (int i = 1; i <= 5; ++i) {
    sum += i;
}
</syntaxhighlight>
The ISO/IEC 9899:1999 publication (commonly known as [[C99]]) also allows initial declarations in {{code|for}} loops. All three sections in the for loop are optional, with an empty condition equivalent to true.
