Library FunctionsRANDSynopsis#include int rand (void)DescriptionThe rand() function is a pseudo-random number generator. It returns an integer in the range 0to 32767, which changes in a pseudo-random fashion on each call. The algorithm will produce adeterministic sequence if started from the same point. The starting point is set using the srand() call.The example shows use of the time() function to generate a different starting point for the sequenceeach time.Example#include #include #include voidmain (void){time_t toc;int i;}time(&toc);srand((int)toc);for(i = 0 ; i != 10 ; i++)printf("%d\t", rand());putchar(’\n’);See Alsosrand()185
