"When comparing strings in C, we cannot use the numerical comparison operators such as ==, or <. Because strings are represented as arrays, using these operators actually compares the variable’s memory addresses. For example:\n\n1 char *a = (char *) malloc(sizeof(char) * 13);\n\n2 char *b = (char *) malloc(sizeof(char) * 13);\n\n3 strcpy(a, \"Hello World!\");\n\n4 strcpy(b, \"Hello World!\");\n\n5\n\n6 if(a == b) {\n\n7 printf(\"strings match!\n\n\");\n\n8 }\n\nThe code above will not print anything even though the strings a and b have the same content. This is because a == b is comparing the memory address of the two variables. Since they point to different memory addresses, created by two separate calls to malloc(), they are not equal."
