codeblocks - C++ Infinity Sign - hello wondering how can display infinity (∞) in c++? using codeblocks. read couple of q&a's on topic i'm newbie @ stuff, hex coding , stuff. have include , type out exactly. if can write code , explain it, that'd great! thanks! the symbol not part of ascii code. however, in code page 437 (most of time default in windows command prompt english language locales/us regional settings) represented character #236. in principle std::cout << static_cast<unsigned char>(236); should display it, result depends on current locale/encoding. on mac (os x) not displayed properly. the best way go utilize unicode set of characters (which standardized big amount of characters/symbols). in case, std::cout << "\u221e"; should job, unicode character #221 represents inf . however, able display unicode, output device should back upwards utf encoding. on mac, terminal uses utf, windows command prompt ...

for loop - sapply or other apply function in R - i wrote code yesterday , confusing help. sorry that. wrote 1 time again in easier way. my question is: there easier (or faster) way implement next code? k <- c(.04, .08, .12, .16, .2); library(plyr) valfcn <- function(k, v_next){ <- .3; b <- .6; return_val <- vector() for(i in 1:5){ tmp <- vector() for(j in 1:5){ tmp[j] <- (log(k[i]^a - k[j]) + b*v_next[j]); } return_val <- c(return_val,max(tmp[i])) } return_val } v0 <- c(rep(0,5)) v1 <- valfcn(k,v0) v2 <- valfcn(k,v1) v1 v2 i'd utilize alternative way might shorter faster, instead of using for-loop method. best! i believe sapply() isn't necessary based on description. might you're looking for: valfcn <- function(k, v_next){ <- .3; b <- .6; max(log(k^a - k) + b*v_next); } in version, transformation beingness done k produces vector , max() operates on entire vector. no n...

bare metal - How do I add a delay of 150 cycles on ARM? - changing pull up/down resistors gpio pins on raspberry pi requires waiting 150 cycles after enabling , disbaling clock signal according specs. doing bit longer doesn't wound using timer wait longer magnitudes don't want that. have simple busy loop: for (int = 0; < 150; ++i) { asm volatile (""); } 0: e3a03096 mov r3, #150 ; 0x96 4: e2533001 subs r3, r3, #1 8: 1afffffd bne 4 <foo+0x4> that loops 150 times, executing 300 instructions. without instruction caching , without branch prediction more 150 cycles. 1 time turned on loop runs way faster, faster 150 cycles think. so how wait close 150 cycles or without instruction caches , branch prediction enabled? note: worst case 2 functions, delay_no_cache() , delay_cache() this not duplicate of how delay arm cortex m0+ n cycles, without timer? since instruction cache , branch prediction completly t...

MySQL Swap Values(not between fields) - i'd inquire help swapping values within single field. table goes this: table field1 field2 x hello y test basically i'd swap x , y values(x becomes test , y becomes hello). know how swap or move values between fields i'm having difficulty this. sorry lame table illustration. this job successfully update rules rule1 bring together rules rule2 on ( rule1.rule_id = 1 , rule2.rule_id = 4 ) set rule1.priority = rule2.priority, rule2.priority = rule1.priority ; mysql
