BASIC had the FOR-NEXT loop back in 1964.
10 FOR N = 1 TO 10
20 PRINT " ";
30 NEXT N
C language would first release in 1972, that had the three-part `for` with assignment, condition, and increment parts.

This reminds me of a little bit of trivia. In very old versions of BASIC, "FORD=STOP" would be parsed as "FOR D = S TO P".
I found that amusing circa 1975.
In Fortran, it is a do-loop :)
Fortran has grown a lot over time. If somebody said it don’t have a do loop in 196X, I wouldn’t be too surprised.
Really it’s just syntactic sugar, just use a goto.
FORTRAN IV, at least the version I used on the PDP-11 running RSX, did not have a DO-loop. Just IF and GO TO. But it did have both logical and arithmetic IF.

The entire point of Fortran was being an effective optimizing compiler for DO loops.
